Years ago I had a small hole that developed in a fuel tang on a Fiat. There was this stuff, it was two parts, had to fold them into each other kind of like silly putty. After prepping the problem area I applied the patch and never had another problem with it. Was it JB weld...can't remember? But I was impressed.

Kewrmit hit the nail on the head!
Part No. 8267-S
Quick, easy and clean. J-B STIK Weld is a hand kneadable, steel-reinforced epoxy putty adhesive/sealant that will plug holes and make permanent repairs on wet and dry surfaces. It will even cure completely submerged in water or GASOLINE! Simply knead thoroughly, with your fingers, a portion necessary for the repair and apply. J-B Stik will fully cure 20-30 minutes; and can be drilled, sanded, filed, tapped, machined, and painted. J-B Stik requires no tools or "prep time", and makes no mess.

If this is just a beater and the hole is small I'd get a screw of appropriate girth (keep it very short though), coat it thickly in JB-Weld, and screw it into the oil pan. Let set for an hour or two then smother some more JB-Weld on the outside.

If this is a nice truck or you go offroading much I'd fix it right. It would suck for that patch to fail and the hole get bigger out deep in the woods.

That's a good way to fix pin holes. Buy more than you need and be prepared to chase leaks - the Mustang has about 4 patches now. Once the rust gets started in those thin tanks, the leaks just keep on coming.

POR-15 used to sell the 2-part epoxy ribbon described in the first post.

I've heard of people welding oil pans, even full of oil. Heck, I understand its not uncommon to see someone weld a leaky diesel tank back together.

Anyone got any more info on this?

the guy my dad had fix his gas tank in the 70s used Bondo
i say drain the pan and weld it. Welding with oil in it should like a fire hazard to me

ckelly is right about chasing the leaks,i had a 351 that had been sitting on a garage floor for years,the pan had started to rust and i ended up spending more time than it was worth trying to patch that thing-get another pan and save yourself the headaches
