Hole in tank fix?

I've brazed, and sometimes soldered tanks (A lot of them). On plastic tanks, I've Plastic Welded them.


When that wasn't an option, I used a 2-Part Gas Tank Repair Epoxy like Permatex #80884. Water Weld (made by JB Weld) used to be really good for repairs too, but the quality has gone downhill.

I used 2-Part Gas Tank Epoxy to fix a leaking drain plug on my '87 D50 in '04, while it was pouring gas out like a waterfall. Drove that truck for 6-7 years with that epoxy crammed around the drain plug. In '10 or '11 when I stripped the truck down, I tried to remove that drain plug to empty the gas out of the tank, I couldn't remove it.

I had a pipe wrench on the drain plug, with a 4' cheater pipe on the end. The epoxy and plug wouldn't break loose, I ended up putting so much force on it, that I rotated the whole tank to the point where it mangled the gas tank mounts instead
