I'm going to replace my fuel filter. But reading the posts in this thread, I came onto something that has bothered me for a while.
I used to remember that when I took off my gas cap at a gas station, it would 'whoosh' as it relieved pressure. Lately, I get no pressure release at all. No matter the temp or anything.
And I've been having fuel ehsitation problems.
Should my gas cap retain pressure that is evident upon release? And if it has no pressure when released, where do you think this lack of pressure originates frrom? Could it also be a contributing cause to the hesitation?
