Gas tank repair question
What can i use to patch up a 5/16 hole i drilled by accident into my gas tank? I tried some putty stuff but not too impressed (still leaks). Can JB weld be used on gas tanks and how do you put in on such a big hole?

There used to be a product you could get at parts house that would seal a tank with fuel in it. It was popular with 4wheelers. I don't know if it will seal a 5/16 hole. It was more for seams and cracks. You could try a self threading screw with a rubber washer and then use the sealer to seal the screw and washer to the tank.

Just ask around and you can probably pick up a good tank for next to nothing. So many people are removing the behind the seat tanks and putting a tank in the rear, that they're readily available.
I just gave one away a couple of months ago.

He said a 5/16 hole---pretty good size for a sheet metal screw to fill.. Personally I would take it down to the local radiator shop and have it repaired ------the right way. It is gasoline were talking about.

I agree, go to a rad shop. you can have it boiled out to remove all the varnish and rust for little to no extra cost, and have the filer neck inspected too. (Very common leak area on these tanks)
If you want to spend a couple more bucks, then you could dump in a POR15 fuel tank liner kit after getting it cleaned. |

Rad shop or weld it up yourself if you have the equipment. If you are going to weld it write back and ask how, as it can be dangerous if you don't do it right.
