Buy some wd-40 in a gallon can. Pour it i the tank, maybe 1 cup. shake it a few times then let it sit. That gunked up stuff will come loose and pour out. It will take a few to clean it enough to allow some Kreem or other fuel tank liner, to work. It's one of the few things wd-40 actually works on.Quote:

I looked on eBay, but everything looked like the same condition. After looking at this thing again, the metal is pretty thin. I can't imagine doing that much spot welding would be fun.
Is it the old Gravely?
Find appropriate size aluminum keg and go to town fabbing.
Yep, the Gravely.
All right, never mind everyone. Once I broke a chunk of the sludge off the wall, it's all been breaking loose now. Now when I stick a flashlight in the tank I can see mostly metal. and the nuts keep coming out when I dump the water. Before they would just get buried in the mud and stay in there. I think spraying the hose into the bottom opened up a spot and now fluid can get under the sludge layer and is helping. Now I just need to get a new petcock and move on to the next thing. Thanks for the help on this, as usual.
I know you've resolved it, but Chemtool B12 is the Colonel's 11 herbs and spices of polar and non-polar solvents. That shit breaks anything loose.
Thank you for the help everyone. I've gotten all the crud out of this tank and used the POR-15 metal prep and tank liner. Now it's drying for the recommend 96 hours. I wasn't really documenting, but if I get this Gravely started I can update if anyone is interested.
On a side note, apparently POR-15 stuff is all the rage right now with off-road guys. My neighbor used it to paint his axle a few months ago. This stuff is still bright and shiny, to the point that every time I look at his truck, I think he's got some new leak. Turns out it's just anywhere that he touched up some paint. The paint is black and it looks like an oil spill. Anyway, I had a cross member to weld up, so he let me use what was left in the can. No exaggeration here, the film that hardened over the top was so tough, that I needed a flat blade screw driver AND a hammer to punch through it. It didn't crumble away once I punched a hole either, I had to peel that layer up like the lid of a beer can. This stuff is TOUGH. I recommend their paint, I hope the tank liner is as tough.
Here is the paint when dry on my cross member.
