My fuel tank is leaking!

Hi, I'm the new owner of a 1982 Pontiac Trans am that I imported to Greece from California few days ago. Yesterday I went to a gas station to fill up my car for the first time and when I returned back to my home I noticed that fuel was leaking from the gas tank. The gas tank is looking in great condition from outside and before my visit to the gas station (it had only 1/4 of gas left) it did not leaked...

Examine exactly where the leak is coming from.. Is it the tank, or the lines.. Dont attempt to fix, buy a new one..

Look around the straps. Mine was leaking there. It's an easy replacement as long as you can get parts in Greece.

It looks like the leak is from the filler neck. At the straps there is also a stain from fuel...

Lots of people have/ had this issue. Myself included.
You'll have to remove the tank. It's not hard but not overly fun either. If the inside/ outside of the tank looks good, (you said that maybe around the straps) you can have the filler neck re-braised. Any rad shop can do it.
Correct me if I'm wrong guys but there is only one company that makes a new tank for this gen of a Camaro. I bought one and it didn't go well. Read my posts in this thread: https://www.thirdgen.org/forums/afte...-gas-tank.html

What? Lol. Tank replacement is simple.



All parts you see here I got at autozone.

Remove the cat back, lower the rear end, remove straps and take out tank. Install new tank in reverse. I replaced pump and sending unit too. Only doing this once!

Re: My fuel tank is leaking!

I know this was discussed many years ago but I dont remember if anyone was successful.. can a plastic tank be installed in these cars? Are the 4th gen using plastic tanks?

No. I tried to get one and all I could get was metal.

Re: My fuel tank is leaking!

plastic LS1 tank will fit, that's what I have... you need to do a bit of wiring tho.

Also, I was never able to find a step by step guide for rear end removal, so I put together one in my build thread.
