So as previously posted, I am having some problems with my fuel system. When I got fuel and unscrewed my gas cap I noticed that I had a lot of pressure release. I did not know if it was normal because I have not driven the van much since owning it. So I currently have a leak at the fuel filter on the motor. I can hear pressurized air leaking from around the filter after the car has been turned off. I am wondering if the fuel regulator can be the culprit. If so does anyone have any tips on replacing one?

Thanks,

William
