I prefer to mig-weld them. I run about 5 psi through the tank while welding.

we flushed it out first.
brazed it up.
filled with water checked for leaks.
drained and re brazed a weeping whole.
re filled with water let sit re checked it for leaks,
all ok drain out water flush out with some diesel,
to stop flash rusting.
fill with old gas drain, fill with good gas.
go for a ride.
that's what i did hope it helps.

I repaired a rub through hole with epoxy tank and radiator repair kit. About 5 dollars from Autozone. Still working great.

I repaired a couple of pin holes in an auxiliary fuel tank for our combine last summer with POR-15. They provide a strip of gauze fabric that helps hold the sealer over the area. It worked great and the tank is completely sealed.

I have them leaded up at a local radiator shop. Lower heat and less chance of a blow out from welding. Brazing is about the same. Make sure the inside is clean. Acid wash with a good rinse works well. A por-15 coating also helps.

needs to be purged out with argon or nitrogen to prevent fires, after its properly cleaned. thats a contiuous purge not just filling it up too.
