There are products that will treat the internal surfaces of a fuel tank to
stop the rust. I treated my MGB tank but at 12 gal. it's much smaller and
easier to work with. Basically you remove the tank and rinse it out, dry it
& pour the mixture in - then turn the tank all different way so the mixture
will coat all surfaces - then repeat 2 more times I believe. The special
coating covers all surfaces & hardens as it converts the rust to some other
stuff -
Eastwood and others sell it. POR probably has a product also. Of course,
for all the trouble it is you might be better off finding a good used tank.
Take care -

What's the best way to get at the tank internals? (I might be forced to
look it up in the manual!)

be rust from inside your tank (or if you're lucky the station's tank). I
got a bad load of diesel in my 126 300SD a few years back and had similar
problems. The in-tank screen filter would gradually clog while driving
and
I'd lose power. After draining the fuel tank I washed it with a pressure
washer shooting through the gage hole while the water and crud drained
through the filter hole below. Then I dried it for a couple days using a
shop vac on blow. But the once-shiny inside of the tank was dark and I
suspect that was partly rust from the water. I also had to disassemble
and
clean the fuel gage (be very careful here) to get the gook off the wire
and
sliding contacts. All has been fine ever since so I'm keeping fingers
crossed and I add biocide at every fillup.

Subject: [MBZ] Mama's Benz got Max's bug
Said her SD had been losing power, not getting up to speed, so yesterday
I changed the in-line filter, took it out and was running fine. The
filter had a lot of gritty sh*t in it, mixed in with some slimy black
sh*t (BTW that word is a technical term). See attached pic. So then
last night we head out to dinner up the other side of town and it was
running fine, we get into town it starts not wanting to go 40. Then we
get to the bridge (where Max had his troubles) and going up we slow down
to like 30 then get over and make it to the restaurant. Head home later,
running fine, we get about halfway home and it starts again not wanting
to go over 40 then 30 then 20 then we limped into the driveway going
about 15. I am guessing it is OK until it pulls enough nasty fuel into
the tank filter to clog it up, then after sitting awhile it sloughs off?
I guess I need to pull the tank filter and see what kind of nasty sh*t is
in there. I am lazy so I will ask y'all how to get into the tank on a
126 and pull and clean the filter.
