I have a 91 z28 305 tpi camaro and its been having a problem lately. When i drive it around and then go to park, i smell gas fumes. I noticed it would happen more during the summertime due to the heat. Now even when its not hot, the smell still occurs. Whenever i would go to get gas and undo the gas cap, pressure would release and sometimes even push the cap off lol. Anyway i havent a clue to what this could be. Any help?

I think most would say that your CCP system isn't working right.

I would also check to make sure the heat shields are in place between the fuel tank and the exhaust pipe & muffler.
