I have a 300zx Twin Turbo 1993, the gas tank is leaking gas. I just want to know how to repair it. Or is it good idea to replace it? Thank you! ---

depends why it is leaking and your plans for the car.If you just want to get a little more time out of a rusty tank use an epoxy repair kit, Napa sells a good one. If it’s keeper get a new tank or a rust free southern tank. If it’s just a small puncture in a otherwise good tank use J B Weld. ---

Jb cold weld is plumbers epoxy…just get some of that and slap it on there. I had a car that was covered in that stuff. Saw a hole and popped some epoxy on it. ---

Is the car, by any chance, lowered? I see a lot of import sports cars that get slammed to the pavement. Then when you go over bumps, you scrape the gas tank. Eventually you wear a hole in it. If your car is lowered, it may well be lowered too much. You’ll want to put it back to factory height (or a less extreme drop) before you drive it on the repaired/replaced tank or you’ll just do it again.
