[Amc-list] gas stank

[Tom Jennings <tomj@xxxxxxx>]

Welp, found a way to deal with the grotty American gas tank.

I'd drained it of gas and left it out so that it would get hot in the
sun and dry up. Turned out to be the right decision -- all the foamy
gunk dried up and came off easily with the fat chain in the tank. I got
a good two quarts of dry stuff out of there. Followed that with a quart
or two of garage floor cleaner (aka that purple degreaser) and the
chains got it a lot cleaner.

It definitely sat for a long time. There was a lot of fluffy rust on the
top of the tank. 

I used FAST ETCH (acid rust remover) and the chain but it was a bit
hopeless; too much rust.

So I cut two 5" diameter holes, one top and bottom, in flat sections. I
putty-knifed all the undercoating off it, and my local machine shop will
hot-tank it overnight. Hopefully that'll get the fluffy crud out.

When I get it back, I'll attach sheet steel patches with sheet metal
screws every 1/2" staggered, with JB weld under it, the metal roughed up
first. Then I'll put in two quarts of tank sealer, probably this stuff

So much for "just driving it". :-)

PS: The tank is pretty interesting, very Rambler Mentality. A typical
tank, two halfs seam welded. The interesting (R.M.) part is that the two
halfs are completely identical; there's knockout areas for the filler
neck and sender hole.

It also means you could construct a good tank from two bad ones, if it
came to that. Don't throw out nuthin!
