When I open the gas cap, a lot of pressure comes out. Is there a way to get a deeper, but simple clearing of it. The truck is parked out in the midwestern heat constantly so thats the cause, but how could I get rid of it under the hood. It'd be nice because to get it out because it makes it hard to start sometimes.

Vent valve may be stuck closed. Have a shop check it with a scan tool to verify.
