I think you can't go wrong with vinyl ester, without sloshing compound. 
I've run over 5000 gallons of auto fuel through N56ML over a 6 year
period, and well over 1000 gallons with ethanol in it...no problems. 
This is the stuff that AS sells, Derakane.  I wouldn't put sloshing
compound on top of that.  Some have no problems with sloshing, some do
have problems.  If it's not there, it can't come loose and clog up the
outlet.  If you look hard enough, there are versions of Derakane that
are even more fuel resistant, but only sold by the 55 gallon drum, best
I can tell.

For those who haven't seen it, for how I built my tanks, see

race)

First..Mark L

I Just resubscribed to the list due to my own lack of computer skills
please disregard...

Now for my question:

What is the consensus on sloshing compounds?

I am building with foam and Vinyl Ester. The smell doesn?t bother
me but I wear an organic respirator when using it. The wife requires
immediate shower and a wash of my clothes however, so it must be not
nice.

The Martin Hollmann book on building Composite Aircraft Recommends
PR-1422A-2. However that book is from 1993 and in SOME places on the
internet this material appears to be obsoleted in favor of
CS3204A2-1/2P especially if you want an endorsement by Cessna.

What about Randolphs? 

Hirsch? 

Thinned out ProSeal? 

Others?

Thanks

I don't know that it was Safe-T-Poxy that was the problem, but most of the 
epoxy resins have issues with alcohol.  My tanks are Safe-T-Poxy (although I 
built them) with a sloshed finish and have been in service for nearly 20 years 
now with no ill effects.  At the time that I built them, what was known about 
vinylester vs epoxy was significantly less than what is known today.  If I was 
building them today, I would use Vinylester.  

A few years ago I rebuilt a set of tip tanks from a Cherokee 235 that were made 
of polyester.  The owner claimed to have been testing his fuel for alcohol, but 
the tanks had softened to the point of them visibly deforming from the air 
pressure in flight.  I rebuilt them by cutting out the end bulkhead, and 
grinding the insides out of the tank, then building a new tank inside the tank 
by building it up and lining it with glass and West Epoxy.  The rebuilt tanks 
have been in service for close to 10 years now with no ill effects, but I 
warned the owner to only use Avgas in the tip tanks as his alcohol testing 
process seemed to be somewhat deficient.
?
Iowa is big on alcohol fuel as the alcohol production helps drive the price of 
corn, which means profits for the Iowa Farmers and local economies.  Can't 
blame them for that.  In Iowa, 85% alcohol pumps for flex fuel vehicles are 
pretty common at the gas stations.  I'm all for having 85% pumps at the gas 
stations for flex fuel vehicles.  But most of those gas stations also carry 
alcohol free premium as well.


Thanks Steve,
I don't know how many of the tanks like mine were produced or delivered but 
they will not stand up to the alcohol content of todays auto fuel. Glad to hear 
you have made the change from the Saf-t-poxy. .The tanks with the saf-T-poxy do 
not have any issue with fuels other wise, I just am of the belief that a fuel 
tank should be safe for everything.
Caution political content: I recently heard a interview in the Iowa voting that 
the guy was going to vote for whom ever supported more ethanol content in 
fuel

Joe,

We primarily only use vinyl-ester now on the tanks we provide unless
requested otherwise.  We have also used Jeffco Epoxy (now Rhino) with good
results. We have had a test sample sitting in Fuel with alcohol for several
years at Richard Shirley's with no deterioration. All my personal tanks have
been built using the Jeffco. They also have a coating that can be painted on
or sloshed during construction and is impervious to the alcohol. Lancair
recommends using it during the construction of their tanks.

Joe,


The fumes are the only real reason. When I built my fuel tank, the garage I was 
building it in was right below my bedroom. My wife was not pleased with the 
smell, and I didn't like it my either. It was a couple days before we could 
breath again. I am convinced West System will work with non-ethanol fuel 
because it is what I used to seal the edges and seams when it started leaking 
and has never leaked since. Luckily, I've pretty much manged to stay away from 
ethanol, but have heard enough horror story's form others to get the the point. 


Thanks,


Rob

Rob,
Is the only reason that you would not use the Vinyl ester because of the fumes? 
I have tanks in 357cj made of both vinyl ester and saf-t-poxy (I think I 
recall) The wing tanks are the vinyl ester and never been a problem with any 
and all types of fuel. But the header tank that I got from Rand Robinson was 
made with saf-t-poxy that is supposed to be for fuel. The first time I had to 
use auto fuel with ethanol it eroded the epoxy of the interior of the tank to 
the point that there was a coating through the entire intake system. I only 
discovered it before an accident because the aerocarb slide was sticking. I had 
to cut open the header tank and re-coat the entire interior. (you could 
actually see where the fuel level had been while the ethanol fuel was in the 
tank) The intake system was dismantled and cleaned. The combustion chambers 
appeared to be OK as it probably burned the resin up. The fuel was only in the 
tank for about 5 days before being used up and replenished with av-gas. The 
fuel that did the damage was 5 gal of Sunoco 93 oct. which was the only thing 
that i could get at the end of the day on a Sunday on the way home from the 
Tennessee gathering.
I do not know if the west system would hold up to fuels although it has not 
harmed the skins of 357cj in any way that I am aware of.
The header tank I am making now is being made from a solid block of foam shaped 
to the configuration that fits under the foreword deck. That is why I am not 
using the 1/4" last-o-foam as the shape is not conducive to flat sides. The  
flat sided type of construction is what I did use on the wing tanks of 357CJ.

KR> fuel tank glassing

[Jeff Scott]

Joe,

My fuel tanks were constructed in just about exactly the same manner as Rob's, 
only a few years earlier, so were constructed with Safe-T-Poxy.  There was lots 
of chatter at the time about epoxy resins not standing up to certain fuels, so 
I chose to slosh the tanks with an alcohol resistant tank sloshing compound.  
I've heard several times that the slosh compound will slough off, and that it 
has a 10 year life span, but after nearly 20 years, is still looks like new.  
Nothing has sloughed or flaked off, which perhaps may be due to the sloshing 
being done on uncontaminated virgin tanks.  My tanks have been exposed to 
alcohol a couple of times over the years, but never a steady diet of alcohol.  
I have run mogas almost exclusively for the last several years and still show 
no issues.

Keep it simple. As long as you factor in the permeability of balloon latex. 
You'd have to subtract the permeability losses over time to calculate the scope 
of a leak. I dont have the permeability of latex to air molecules (if you arent 
using another gas with larger molecules), but you should also consider the 
effects of the latex formulation, thickness, ambient temperature, humidity, and 
of course pressure.  Once you have those calculated, you should be able to 
determine the volumetric losses at the balloon, and then you can know the 
losses (if any) at the tank being tested.

Ever since I saw this written up on Mark's page, I thought it was one of the 
most forehead-slapping moments I've ever had, as in "why didn't I think of 
that?".  After trying to figure out how to shape and pre-wet flanges or angles 
upside-down inside the top of the tank to make sure the closure panel was fully 
seated and that the seam was wetted out, Mark's how-to-do-it sequence answered 
that question perfectly.  In case you haven't seen it, go here and scroll down 
to the tank construction: http://www.n56ml.com/900hour/ , with the key photo 
being this one: http://www.n56ml.com/900hour/100717014.jpg .Duct tape, spring 
clips, and a piece of metal angle.  Couldn't be simpler.

Yes you use a regulator on the air line or use a hand pump or be quick 
on the disconnect.
Your air compressor may have 150 lbs in the tank but you can still 
manage to fill a tire with 35. You would only need 2 lbs air to test the 
tank and if? your in a hurry to do a bunch you could put the tank under 
test in a tank of water and look for bubbles.
As already pointed out the balloon idea will change pressure with 
temperature and there really is no way to know if it truly is as large 
as it was 2 hours before. The gauge method I wrote on however is 
accurate as the gauge doesn't lye.

Yes you use a regulator on the air line or use a hand pump or be quick 
on the disconnect.
Your air compressor may have 150 lbs in the tank but you can still 
manage to fill a tire with 35. You would only need 2 lbs air to test the 
tank and if  your in a hurry to do a bunch you could put the tank under 
test in a tank of water and look for bubbles.
As already pointed out the balloon idea will change pressure with 
temperature and there really is no way to know if it truly is as large 
as it was 2 hours before. The gauge method I wrote on however is 
accurate as the gauge doesn't lye.

KR> Fuel tank pressure test

[Teate, Stephen]

One thing I didn't see mentioned here is to use extremely LOW pressure. One to 
two pounds through a regulator. Don't think you will be fast enough to just 
shoot a little in there. Otherwise your square tank will become streamlined. As 
usual don't ask how I know this.

To pressure test a tank you use a pressure gauge connected to a T fitting
screwed in to the tank.
One of the T connections to the tank
Another to the pressure gauge
The third to the valve
Open the valve to allow air to go in to the tank Close the valve and make
sure the pressure doesnt drop after a set time say 24 hours.
Open valve to vent the tank and then unscrew the T.

It's worth reminding folks that we are talking very low pressure here, 
in the order of one PSI or less, if you don't want to blow up your tank. 
  I've checked my lungs with a high resolution pressure gauge, and I can 
bearly blow 1 psi, for an instant.  The balloon method prevents 
disasters that can happen when using an air compressor for this job. 
Personally, I build the bottom of the tank and fill it with gasoline for 
the night, and come back and check it the next day, then install the top 
onto a bed of flox, and glass the outside of the joint again.   By 
filling the bottom, you at least prove the critical bottom four joints 
are good before you button the whole thing up.  If it leaks around the 
top, you can either fix it or don't fill it quite all the way up. 
N56ML's header tank was that way, but I learned from the experience and 
never had another leak on the other two tanks.

Don't bother with a water test.? You can have pin holes that will not 
pass water but will allow the entire take of gasoline to drain over time.

KR> fuel tank for kr2s

[Jeff Scott]

Aluminum tanks seem to be the choice of today, but 20 years ago, I built mine 
with Safe-T-Poxy, then sloshed with alcohol resistant sloshing compound.  While 
many have told me the slosh compound has a 10 year life, at 20 years, I see no 
indication of any kind of degradation in it.  Perhaps that's because it had 
several months to cure before it ever saw any fuel.

Like Mark, the glass tanks were quick and easy to build and have been 
absolutely trouble free for nearly 1100 hrs of flight time.  While I have 
exposed the tanks to alcohol on a couple of occasions, I generally only feed my 
plane alcohol free Mogas or 100LL when that's the only choice.

Nothing wrong with building tanks of Aluminum. It's a good solution, but also 
comparatively tedious and time consuming to build.  But once built and sealed 
with ProSeal, it's going to last forever.

After hearing all the time, pain, and cost that Dan Heath went through 
to build his aluminum tanks, I'm still using vinylester, foam, and 
fiberglass.  I built an 8 gallon wing tank in one day (way less than 
eight hours of actual work) a few summers ago, and it's never leaked a 
drop.  Vinylester is impervious to ethanol and autofuel, and I've never 
had a problem with it, despite running at least 5000 gallons of it 
through my tank.

There is something to be said for aluminum...generally if it doesn't 
leak in the beginning, it likely never will, and you don't have to worry 
about what kind of fuel you're putting in it, but you may discover 
issues with the sloshing compound later on.  But I'm sold on the speed 
and simplicity of the glass tanks.

There are links to the tanks I've built so far at
http://www.n56ml.com/kft.html
http://www.n56ml.com/kft.html and
http://www.n56ml.com/900hour/

The last one shows how you make a "ledge" to set the top on as a last 
step.  Once you have ledges all the way around the top, put a generous 
bead of flox on it, all the way around, and then press the top in place 
and weight is down at the ledges to insure a good seal.

KR> Fuel tank venting

[Paul VISK]

I hope I can explain this ok.?I have a stub wing tank and a outboard tank. The 
inboard tank will be sealed closed. The engine fuel supply will come from that 
tank. ?I have a vent line between the two tanks that has a dip ?between the two 
tanks were (I think) fuel can spill over and accumulate.?The question is. Is 
that a problem? Will this prevent venting or will the air just force its way

I seem to recall a "fire retardant" foam or some substance that you 
fill the tank with that helps contain the fuel in case of a tank 
breakup but I know nothing about it.  Others can chime in.  Seems 
like it is used in tanks on race cars, boats, etc..  You might try 
looking on race sites for more info.  Or, if the tank is assessable, 
you could just install foam baffle too.  Just make sure you don't 
build in any air traps, i.e., cut holes in the very top of the 
baffles for air to escape all sections of the tank when filling.

Seeing no replys to your question I'll throw something out.  The 
statement saying " I received a tank with no baffles doesn't give us 
much to go on."  It would help to have more info on the tank.  Where 
did you purchase the tank?  Is it sealed or can you get to the 
internal part of the tank?  What type of resin was used to construct 
the tank?  Does the tank have fittings attached?  Size of tank and 
where will it be located in the KR?

Foam baffles will work if you can incase them in glass and resin.  I 
built my tanks in the outboard wing panels using foam and glass for 
the entire tank, including baffles.

I agree completely and meant to write that earlier.  I spent a lot of time 
fretting over that very same issue, but the KR's differential aileron 
controls help ensure that the ball will be either perfectly centered or very 
close to it during just about all regimes of normal flight except takeoff 
and slips and that sort of thing. In the 1130 hours I put on N56ML, I only 
heard the engine starve for fuel once, and that's when I deliberately 
starved it just to see how long it would take to restart (and that was at 
5000', probably).

And there was a comment about why Cessnas don't have a problem with that. 
It's pretty clear that if you have two tall stand pipes that terminate in  Y 
or a T at the carburetor at the bottom, you can leave them both unported at 
the top...as long as there's fuel standing in at least one of the pipes, the 
carb  will get fuel.

hi guys...it seems to me that if you ran a line off the roll-over vent to the 
rear of the plane(out the bottom ) if you put it on its nose the end of the 
line is higher than the tank (no loss of fuel) and if it went over on its back 
the check valve should work (hopefully no fuel)   brad davis

KR> fuel tank

[Margaret Davis]

hi guys. i hope everyone had a nice x-mass..im looking at a fuel tank from 
summit racing for the kr-2, its a fuel cell with roll over vent-16 
gal-plastic-dual outlet-2inch sump-aircraft foam-with a fuel gauge  it looked 
like a good way to go to me  any input  thanks  brad davis

KR> Fuel tank pick up and vent

Given that 32mm is the diameter of the Rochester carb on just one cylinder
(3) bank on the stock car engine, my feeling is that a single 32mm carb
would be too small to feed both banks (6) especially at higher revs. What do
Aerocarb say?

The carb came with a kr2s project I had purchased and if it doesn't work out 
I will
do something else.  Thanks for the heads up on the vent being near the 
exhaust
stream.  I will check that when I get the engine on but shouldn't be a 
problem.
That is a good note for the rest of us builders out there.

Thanks again,

[joe.kr2s.buil...@juno.com]

Hey guys,Let me see if I convey this with some sort of reasoning. First 
history: I started out with aerocarb set up with a fuel pump and a regulator 
and ram air on a corvair. The fuel tank is vented from the very very top of the 
tank and sloped down hill behind the panel and out the side of the fuselage 
just in front of the wing about 7" up from the top of the wing on the passenger 
side. It is comprised of a 1/4" alum tube inside the tank and to the outside of 
the tank, the vent is then 1/4 " clear tubing to the side of the fuselage and 
then changes back to 1/4" alum. tube. The tube through the side is bent in  
somewhat of an crooked S shape so that it points straight into the slip stream 
of the fuselage. The open end faceing front is flared with the flaring tool 
that would normally  be used to install the flared fittings for a AN-4 flared 
fitting. The fuel pump was removed in favor of gravity feed during first ground 
runs. The ram air was removed as problems showed up during taxi testing. The 
slight ram pressure that the vent tube picks up remains after 6 years and 660 
hours. There is a fuel pressure sensor installed low in the system that reads 
to the tenth's of a pound. It never, even with as low as 2 gallons of fuel 
remaining, reads less than .9# at static. And around 1.4# in flight. I since 
added the fuel flow and installed it upstream of the pressure sensor. The 
pressures dropped but not to what i had calculated them to be. The static with 
low fuel is never below .8# and in flight now operates at 1.2# . The head 
height for pressure is 19" sitting level and certainly less in any climb. I do 
not have any back flow preventer installed and my opinion is something 
mechanical in a line that small is something that will get stuck. I got lucky 
and the pressures are centered around the published required pressures for the 
Aerocarb.Steven, I don't remember you saying what engine or what size carb, or 
header tank. The Aerocarb does work and I can not explain some of the problems 
that people have. Given that statement if i had more money 10 years ago I would 
have installed a ellison. My experinces with auto fuel and the Aerocarb are not 
good either.Joe HortonCoopersburg, Pa.-- Forwarded Message --

I've had no experience with Aerocarbs. I suspect it might given they are
reputedly a calibrated "fuel leak" but I don't know. Guess it depends on the
diameter of the vent and thus the amount of pressurisation. Someone else
might chime in or you should contact the manufacturer for the definitive
opinion. A simple vent in a cap will leak if upside in a prang. Use an
aircraft designed one. I think these have some kind of a rubber flap
arrangement that prevents this. Check out Aircraft Spruce.

John

I will be running a areocarb on a corvair engine and was wondering
if running ram pressure into the vent of the header tank will cause a
problem with this carb.  Should I be using just a vented cap instead.

Consider leakage and fire risk in event you nose over.

Vent needs to loop above and then below the fuel level to prevent this.
Refer Bingalis book.
Don't vent to slipstream or suction can empty your fuel tank.

If pointed into wind remember the ram pressure will affect your fuel
delivery and some carbys are sensitive to this.

Not too bad yet - it's still possible in Oz to get regular unleaded with no
ethanol if you shop around, and premium unleaded generally has no ethanol,
but there's talk of mandating it, so not sure how long the current state of

KR> Fuel tank probes

[Jeff Scott]

I have had this model of fuel probe in all three tanks of my KR from day 1, 
which is now over 14 years of flying. They work great when they are working and 
give good stable and accurate information. However, I have had cronic problems 
with the grounding wire that wraps around the base of the probe inside the 
tank. The wire is attached to the probe with a pop rivet, but there is a 
problem with the wire and the probe being dissimilar metals, so even in the dry 
climate here in NM, it gets some galvanic corrosion due to the dissimilar 
metals, which allows the ground on the probe to float. That causes intermittent 
low fuel readings, then the gauge eventually quits. I have replaced all three 
probes on my plane at least once and have had repeat problems with some of 
them. I'm sure others will write in and tell you they have never had a problem 
with theirs. My experience with using these for 14 years and 850+ hours is OK, 
but not as good as I would have expected for something with no moving parts. It 
seems that I get roughly 5 years of service before I have to remove the wings 
so I can pull these probes out for maintenance. That is not satisfactory IMHO, 
but your mileage may vary. :o)

 My recommendation would be to look into the heavier capacitance fuel probes 
used by Vans in their aircraft.

Try this at Aircraft Spruce.  They work with Westach and with Dynon, and

work.  I should be able to give more information on them in a couple months
and hope to be at the Gathering with them in the tanks, in the Black Bird.

Sounds like youre looking for a capacitive fuel probe. Aircraft Spruce sells 
them as a package with a probe and a gauge. 
http://www.aircraftspruce.com/catalog/eppages/skysportfuelsys.php  or just the 
probe itself http://www.aircraftspruce.com/catalog/inpages/princefuelprobes.php 
.  They can be ordered in any length needed and can be cut and bent to fit many 
applications.

I think I remember that you posted an email about fuel tank probes that were 3 
to 4 foot in length that could be fastened diagonally along the tank from 
highest point at the
outboard tip to the low point at the inboard end. I also remember this probe 
mounted within a perforated tube support. Does this ring any bells? I tried 
searching the archives,
but no luck. I'm trying to locate a source for this type of probe and then 
hopefully, find a fuel gauge that will be compatible with the signal output of 
the probe.
Any help on this would be greatly appreciated.

KR> Fuel tank Sealing

[smwood]

Sid.
I was reading your web page fuel tank section, and was wondering what you
used and how you sealed you fuel tank inspection ports, and your unions you
used for the vents.

Phil Matheson.
--

Phil,
My fuel tanks are constructed with vinyl ester resin and fiberglass, same as 
the Diehl skins.  There are no inspection ports in the tanks, except for 
possibly the fuel filler cap.  The cap is the flush fitting set from Rand 
Robinson.  The threaded ring is floxed in the top skin with vinyl ester 
flox.  The fuel outlet, quick drain and vent fittings are aluminum welding 
flanges that are floxed into the walls.
http://www.aircraftspruce.com/catalog/hapages/alumflange.php  I drilled a 
series of holes around the flat areas of the fittings to allow better grip 
for the flox.  Pipe threads in the flanges connect the rest of the piping.
The vents are nylon tubing with mechanical swaged fittings.  The fuel supply 
line is all aluminum with AN flared fittings.  The entire tank and plumbing 
system including the vent pipes have been tested air tight.  All piping is 
supported to minimize movement from vibration.
Each inspection panel in the bottom wing skin to look at the outer wall of 
the fuel tank is made from the piece that was cut out.  The attaching rim 
has no particular gasket or seal.  I figure the panel is on the bottom of 
the wing so rain and wash water would have little possibility to get in that 
otherwise empty bay.

I have a aluminum fuel tank that came as a part of the project I have.  It was 
built by some shop ordered by the original builder.  It was going into a KR 2s. 
 If you are interested let me know ow and I will send you pictures and copies 
of the drawing for the build.

KR> Fuel Tank Vent

[joe.kr2s.buil...@juno.com]

Bob,
   I have the Rand header tank and I Installed a 1/4" aluminum tube at the very 
top of tank pointing forward and a slight slope towards the rear of the tank 
where it exits grouped with the filler tube and the fuel level sender wires. At 
that point I connected a clear fuel line tube and ran it towards the passenger 
side with constant slope to under the shlef and to an exit point. At the exit 
point I bent another piece of the 1/4" aluminum tube going through the fuselage 
side about 2" behind the firewall just below th shelf and the open end of the 
tube faces straight forward which  I flared the end open to scoop up some air 
and in some effect pressurizing the fuel tank. It's never even been a quesstion 
with venting execpt for slow fuel filling for the last couple of gallons of 
fuel. I have on several occasions while transfering fuel from wings to header 
tank forgot and pumped a couple gallons overboard. I have a fuel pressure 
indicator and it always inflight indicates more pressure than is available by 
gravity.

An even more simple way to vent your tank would be to use one of these:

This is what I plan to use on my wing tanks.

A simple 1/4 inch line that terminates in the top of the take will 
work.  It can run to any point where a slight fuel slosh or leak due 
to expansion will not do damage.  The only requirement is that the 
line exceed the top elevation of the tank at some point in the 
run.  If one end terminates in the slipstream, it must be pointed 
forward to eliminate the possibility of a negative pressure.  A line 
through the cap with a 90 or 180 degree bend, similar to aircraft 
from the 20s, 30s and 40s will work.  Anything that lets air in 
without letting fuel out will do.  Keep it simple.

I am to the point of building a new fuel tank for my new fuselage following the

NTSB felt the cause was improper fuel tank venting that caused a vaccuum that 
beat the gravity feed system.

No need to do the machining.  Wick's has the items already made up.
I used them for the quick drains and for my tank fuel pickup.  One
is sized to accept the strainer on the inside and the pickup hose on
the outside. The aluminum stock to build them will equal their cost
from Wick's. I also used the large fuel cap and ring but I didn't see
it listed any more.

http://www.wicksaircraft.com/catalog/product_cat.php/subid=977/index.html

Bond them to the inside of the tank during construction.  I used resin / flox
to fare the edges and then probably two layers of glass to hold them.
When installing the quick drains, sand down the foam to mount them in
a small depression to insure they are the lowest part of the tank.

For the pickup with the internal screen, mount the screen horizontal
in the bottom of the tank.  That allows maximum tank size for a given
area while keeping all the fittings inside the wing plane.  Again, I
sanded out a small depression for the screen.  It sets in a depressed
area with approx 1/4" clearance from the bottom.  That will insure the
maximum useable fuel from the tank.  When setting in a level attitude,
my tanks will pump very near totally dry.

I guess you're right about that, but some folks are like me and would rather 
spend a few minutes with the bandsaw, drill, and tap, using a scrap of 
aluminum left over from something else, and be done with it in ten minutes 
rather than wait for a few days for the mail and spend the $ for the "real

The additional benefit of the "purchased" fittings is they probably
have double the threaded area for the fittings to screw in to over
a piece of 3/8" aluminum.  You're probably better with a hacksaw
and tapper than I am.  It would probably take me the same amount
of time to build them as waiting to receive them from wick's.  :-)

Mark,

Nice documentation on the tanks. I am just getting started on my KR2S but am
interested in the aluminum tanks since it would allow me to run automotive
gas.  I did not see any tabs to attach the tanks to the wing spars.  How did
you attach these?

KR> Fuel Tank Question

[Stephen Henderson]

Hello,

I am considering building some aluminum fuel tanks and was wondering if 
anyone has tried to build one using the aluminum welding rods that you get in a 
tube at Harbor Freight Tools? They are used for gas welding. I know a guy that 
uses these rods to repair boat propellers and it is very strong stuff. I have 
used these around the house for small things for several years and would really 
be interested in building some wing tanks like this because I am pretty good at 
gas welding. Any thoughts or opinions from anyone out there would be greatly 
appreciated.

KR> Fuel tank sealant

[bob]

Anyone have the absolute, hands-down, definitive answer on sealing
fiberglass fuel tanks?  After a couple of days Googling NTSB reports
and builder horror stories I'm afraid to even put a fuel tank on my
plane, at least one that might need to hold fuel with an alcohol additive.

This stuff sounds wonderful, I guess.
http://www.caswellplating.com/aids/epoxygas.htm

I don't need 3 gallons of this, and they don't say anything about alcohol.
http://www.aircraftspruce.com/catalog/cspages/tankseal.php

Randolph 912 is supposed to be another option, but I haven't been able
to find it.

Finally, *almost* everyone claims that vinylester resin is impervious to
fuel with additives, but I was able to find a few posts on the net saying
it isn't.

In other words, I'm confused.  Any advice appreciated.

Thanks,
Bob

Bob:

I have been trying to solve the same problem and have been getting the same
result.

Word of advice though,  the FAA when it issues an STC to use auto gas in an
certified aircraft prohibits the use of  MOGAS containing alcohol.  From what
I have been able to determine it is because of alcohols affinity for water and
they are afraid of fuel line freeze-up and plugging.  Personally that is
enough for me so I will stick to the unleaded MOGAS either 87 or 91 octane.

KR> fuel tank(s)

[Ameet Savant]

Hello all,

I saw a documentry on Discovery the other day about
the early (well, not so early) testing of car fire in
a rear ended collision. The results were just
unbelievable by today's standards. Fuels spilling all
over and causing huge consuming fires in the passenger
compartments. The car industry solved that problem by
putting a rubber liner inside the fuel tanks and the
spillage was bad only in the really bad accidents.

I haven't read about or seen anyone do the same in
experimental aircrafts. Post crash fires are a reality
that we plan for as pilots, but is it possible for us
to prevent them as builders? Any KRs out there with
some inbuilt safety systems against this?

On another note, can someone from the Los Angeles and
surrounding area contact me off the krnet at
ameetsav...@yahoo.com ?

Hope ya'll have a great 4th!

One approach that I took was to remove all fuel storage from the
cockpit.  I have tanks in the outer wing panels only.  My intent was
to place the fuel as far as possible from any ignition sources, and
in the case of a post crash fire, possibly buy me some time to
RUN LIKE HELL

The race industry does the same thing as the military...they use fuel 
bladders (fuel cells).  Typically wing tanks are just integral (no fuel

Agree with point 1. Although I have seen them advertised that way many 
times. When I was selling combat helicopter upgrades (for Eurocopter Pumas 
or Mil Mi-17 or Mi-24), I used the more conservative terminology 
"crashworthy".

And it definitely was beaucoup, beaucoup $$$, especially once I had put my

1.  There ain't no such thing as a crash-proof helicopter fuel tank.

2.  Latest practice is to move the fuel outside the fuselage if possible, 
i.e. sponson tanks.  For KR use, think of the wings as skinny sponsons. If 

you're familiar with the MH-53E/S80-M1, make that very skinny :-)

3.  If the fuel has to be in the fuselage, put it behind the cabin with 
the 
strongest bulkhead in the A/C in front of it, i.e. Blackhawk.  Also, use 
"Breakaway" connections on all fuel lines (boucou $$$)

4.  All tanks do use a "self-sealing" inner bladder (think "bullet-proof", 

up to 20/23 mm) (more )

5.  And, as I mentioned before, internal/external auxiliary tanks use foam 

or "Explosafe" aluminum mesh to prevent fuel from flying around in a 
crash. 
It doesn't stop the fuel from burning, though :-(
Sorry, I don't remember the manufacturer/trade name for the foam.

Hi Bob, 
Take a look at the BK1 website below.  When the front page of the website comes 
up, click on the BK1.0 builders log which is 180 photos of the building 
process. Photos 76 thru 79 show photos of his metal fuel tank that he built. 
There are captions at the bottom of the photos. He built his tank with pieces 
of metal (probably aluminum) that he bent up to fit his plane, riveted together 
and used pro seal to seal all the joints.

Bob, welding it up would be great and I think having a header tank would be a 
safety idea. I like the idea of gravity feed just in case !
My brother who I see almost daily is a certified welder. We have two tig 
welding machines at my factory so I like aluminum welding also. I am a good 
welder but have not taken the time to master tig, so I let my brother do the 
tigging. He can weld beer can skins together with a nice bead so he can easily 
handle a fuel tank. I had him weld an aluminum fuel tank for my dune buggy.
Sounds like you have it made now.

KR>fuel tank

[Russ Fenlason]

I just came across a HDPE tank that is about 16 gallons it is roughly
square.  It seems rather large for a header tank. Does any one know what can
be done with HDPE.  Can it be cut and glued? can it be heated and reshaped?
Any Ideas would be appreciated.   Thanks Russ  (High density Polyethylene)
