Hey guys, I replaced my fuel pump and everything is running fine. I got out of the car after running it for about an hour and when I got out of the car I could hear pressure releasing out of the vent cap. I removed the cap and pressure came out. I know that there would a certain amount of tank pressure, but how much is too much. What would cause too much pressure. The car is running great with no problems since I replaced the fuel pump. Thanks guys, Mike
