I have a 79 z28. The car has always been parked inside with no rust. I bought the car 5 years ago and it has seen very little use, The last 3 years it has been sitting in storage. Last week I got it started again after having to replace the fuel pump and filter. It runs really good going down the road but at ideal it runs a little rough and some times stalls out at idle. It also runs a little hot mid day in Florida. I plan on taking off the carb and having it rebuilt Monday. I am having to drop the fuel tank and replace the sending unit since my gas gauge doesn't work. My question is should I take the tank to a local place for $95 and have it cleaned out or just buy a new tank since I am going through the trouble of removing it. A new tank is about $150 at NPD which is local in Ocala.
