I have a gas tank from a 69 coupe. There is a small leak where the filler neck meets the tank body. I don't know if it's easily fixed. Only leaks when the tank is full...I ran it for a long time just keeping half a tank. Probably not worth paying someone to fix it...but might be fixed with some JB weld around the neck-body joint.
Aside from that, it's a decent 43 year old gas tank. I don't think it's able to be shipped. I'm in Southern Maine/NH. I'll give it a week or so if anyone wants it, then I'll dump it. Just offering in case anyone needs a tank for a project.
