Welding a gas tank
 

Anyone have any experience welding gas tanks? Mine has separated slightly at the pinch seam. I think its just stamped steel. I tried JB weld and epoxy the ---- out of it but it still drips when its full. So, can I do this in the car without A) causing a fire or B) causing an explosion? Or is it just better to remove it?

DO NOT WELD YOUR TANK ON THE CAR.

remove tank, empty fuel, let it sit for a couple days, use a hose to connect an exhaust from another car into the tank, and let it fill with exhaust, then weld only when the exhaust is running through the tank to displace all oxygen inside the tank.

They make a tank patch designed to be applied while on the car and filled with gas still.

fill overflowing with water. clean it, more warter. then weld it.

That would be my sugestion... Idk about the exhaust gass method. sounds questionable to me

Re: Welding a gas tank
 

i like the exhaust gas method. but its a little harder than just filling with water and emptying. finding a hose and all that.
but really, i bet they sell gas tank patches for stuff like this.

Alright, thanks for the input guys. I think I'll look into a patch kit. I really want to repair it in the car because its a saddle tank that sits over my rear steering gear(4WS).

none of the gastank repair kits worked on my wifes 64 fairlane.

we were gonna weld it up, but figured if we fix this leak it's just gonna leak somewhere else next week.
we got a new tank.

If its leaking in one spot, you will fix it only to find more leaks... way safer to get a new one if its cheap man

get some sheet metal and make a new one.
