Anyone have a band saw to cut a fuel tank?

Yeah, I'm going to try more cleaning now that I've made some progress.

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.

Have you looked around for a salvage replacement?

Now you know why I said good luck and you would learn some new skills.

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?

[buffalobo]

Find appropriate size aluminum keg and go to town fabbing.

[Irving]

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.
