Re: Stus-List Fuel Mystery

[David Miles via CnC-List]

Hi Tom,
Is it possible that the tank has a few gallons of microbial growth 
(bacterial and fungus) that gas created clumps/sludge on the bottom of the 
tank taking up good fuel space?
Be careful using a bio ide, as a friend told me he did this and a few weeks 
later while returning through Active pass in choppy seas, some clumps 
blocked his fuel filter. Fortunately he had previously installed a parallel 
filter, and a quick flip of a switch to the backup fuel filter got the 
engine running again with no other problems.

Good luck.

The inner and outer liners of fill hose on Touche' when I bought it were
separated.  The outer liner was bulged out.  Could be just as true that
your inner liner is bulged inward.

Stus-List Fuel Mystery

[Tom Buscaglia via CnC-List]

Al

I had the same thing happen earlier i the 
year.  It turned out the the fuel dock had 
recently installed new high volume pumps, I 
assume to speed up filling larges motor yachts, 
and that, not the fill tube was the issue.  You 
may want to check that before you start tearing out things.

This year my tank started to fill rather slowly. 
Trying to fill faster resulted in fuel backing 
up in the hose. I haven?t gotten to it yet but 
I?ll replace the fill and vent hoses to see if that cures it.

Re: Stus-List Fuel Mystery

[Charlie Nelson via CnC-List]

My pick-up tube had a screen near its end near the tank bottom. 
This screen got plugged up with ‘stuff’ after a few years of boat ownership and 
it cost me a weekend in a yard and a few boat bucks before the yard realized it 
was there. Of course before they knew of its existence they had swapped out 
most of the fuel system and attempted to deliver the boat to me when it lost 
power again. That is when they found the screen!
Cut the POS away and problem was eliminated—who knew!!
Might be worth a look on your boat—don’t think you can see it or do anything 
about it (if it’s there) without removing the pick-up tube from the tank.

The pickup tube is near the forward part of the tank.  Have you done
anything to change the pitch of the boat?  If you removed bow weight or
added stern weight or both, this could change the pitch such that fuel
collects further from the pickup tube.

Re: Stus-List Fuel Mystery

[Edd Schillay via CnC-List]

Tom,

When I put fuel into the Enterprise (insert dilithium crystal / antimatter joke 
here), I often have to go very slow as the fill will back up if I go quickly, 
giving me a false impression that the tank was full. Could that be it?

Also, is there any chance that the boat has a bit of a heel when fueling this 
time? I think, but not sure, the fill is on the starboard side of the tank. if 
the boat is heeled at all to starboard, the port side of the tank would have 
some air left in it.  

These are just guesses as I am also at a loss, and my usual solution to engine 
problems is “get the jib out.” 

All the best,

Edd

The rancor is clean and aside from need to bleed the system down to the

Have at it C sleuths...I am at a loss.

Stus-List Fuel Mystery

[Tom Buscaglia via CnC-List]

I have a puzzle.  I was on my way to fill up last 
trip out for a nice weekend rendezvous with out 
club when I ran out of fuel.  Fortunately, I was 
close enough to our club in the inner harbor.  I 
dropped the dinghy and ran to shore to get a 
gerry can of diesel.  When I finally got to the 
gas dock in Tacoma she only took 24.5 G of 
diesel.  I made sure that the filler tube was 
open and even intentionally overfilled it to make 
sure the vent was clear (than god for my catch 
can!)  I made sure the tank was topped off.


I have never trusted by gauge as it would show 
empty when there was 1/2 a tank left.  I used to 
chart all time and distance religiously in my old 
boat and did the same on Alera initially.  Then I 
realized that unlike out old 35 MK1 Alera had a 
functioning Hobbes meter.  So over the last few 
seasons I got lax and instead of copious logging 
I just take a picture of the Hobbes meter at 
every fill up.  Made sense and eliminated the 
problem of accounting for sailing time on long 
runs.  Based on the Hobbes meter reading from the 
last fill up the engine ran 26 hrs.  Very 
consistent with my established burn rate of 0.9 GpHr.


I started to suspect that maybe the PO had 
replaced the original 40G tank with a smaller 
one.  However, when I checked my log book I have 
had several occasions where the fill up was more 
than30G..  Not many, but more than one or two over the 25G mark.


The rancor is clean and aside from need to bleed 
the system down to the injectors to get her 
started after the stall out, no air leaks in the 
fuel system.  Motoring in flat seas, so sloshing fuel is not it either.


Have at it C sleuths...I am at a loss.
