I have a gas leak right where the filler tube comes into the tank. It's a pretty constant drip. I really don't want to crack it open and take it all apart. I was in the hardware store the other day and got looking at some 2-part epoxy stuff. It's a stick and you just rip off some of it, mash it around, and that activates it. That stuff though said you had to remove all the oil and everything before using it. So I'm assuming it wouldn't work on a gas leak.

That said, do they have such a stuff formulated for gas tank repair? Seems logical.

 

Most auto part stores have kits for repairing gas tank leaks.

 

What year is your van and does it have a rubber boot that the filler neck goes through into the tank? If so the Dodge dealer has the boot (or collar I think they called it) for less than $30.00. Most epoxy's will not stick to the rubber boots.
