M38A1 fuel tank cleaning?

[Casey B]

Is all the gunk on the bottom of the tank?

Yes it looks like it is only one the bottom of the tanks and from what I can see only on one side of the baffle and looks like it was poured in then the tank tilted to the same position as when I took the pictures.


Really hot water ( I sort of suspect this may work)
Acetone
Straight alcohol
Automotive paint gun cleaner

Please keep us posted on how you make out as your problem is one which any of us can end up dealing with

Well I am going to try just plain old gasoline first to see if it loosens then as you said Phil try the Hot watr from a kettle and a wood scraper then the others and see what this stuff is Feels and looks like fuel varnish. No holes in tank so we'll see have a radiator shop in mind to take it to but will try these first!

Rob where do you fit the upper fuel filter before the carb? just along the fuel line that runs to the input on the distributor side of the engine I am guessing?
A plastic fuel line filter is okay there...? heat? or would you go with a metal one? I used a plastic one on the fram rail pass side just near the spring shackle.
Thanks again and will let you know!
