While looking around for a replacement fuel tank for my leaking 83
diesel, I decided to try to stop the leak, if I could, using whatever
such products were available cheap and locally. While it's no permanent
fix, I got tired of losing fuel and stinking up the neighborhood and
figured I'd gamble a few bucks on some snake oil.

I bought Permatex Gas Tank & Radiator Repair, which said nothing about
its use with diesel. My FLAPS didn't have a clue, so I bought it anyway
because it said the it worked even on gas-wetted surfaces.

I used carburetor cleaner on a rag and then sandpaper to clean the area
down to the metal, then mixed up a dime-sized bit and mashed it as hard
as I could into the offending spot. It was still leaking when I did it,
I didn't even drain the tank.

It stuck.

It may not stick for long, but if it buys me a week or so, it will be
well worth the few bucks. Right now it's bone dry.
