Just recently after I drive my car, especially for long periods, when it is parked and turned off the fuel seems to swish in the tank. If I start to take the gas cap off, there is a long period of pressure relief and if I put the cap back on and do it again a minute or two later, it releases yet more pressure.

What could be causing this to happen, too hot exhaust, octane,...? I use 92 octane fuel if that provides and assistance and the rest of the cars setup is in my sig. Thanks

Matt
