I took the Z this week into Tough Guy Industries to get the gas tank removed, restored and replaced. It is a common problem on the Zs, and more especially on a 35 year old car that sat in storage for years. You never know if the tank was dirty inside, rusting, or if it is keeping pressure well still.
Whenever the Z is in a shop... I am like a worried parent wondering when the shop will call, what if its a bad news and I have a huge bill, or worse if the call is saying that the car is no good. I lose sleep, I am searching online for new gas tanks in case I need to buy one, and looking at other Zs in case mine is junk and I need to buy a new car.
After a day of waiting I got a call from them... they said the tank had been removed and restored before. The inside of the tank had a new lining, so they cleaned it for me again, and put it back in. Saves me money, and while she was in there they were able to pull off my bumper shock towers for me, so the rear end of the Z is looking good (you have to remove the exhaust and gas tank to get the bumper shocks out).
Now the down side is that this saving me money, but I have not found the issue with why the Z is lacking power... so the work continues on trying to get her faster! At least I can worry about one less item...
