So nobody else hears a rush of air when they pop their gas cap to refuel?
If I'm the only one, then I assume my vent is 100% plugged... I'm surprised the fuel pump can pump fuel out of the tank under than much negative pressure.. Of course I haven't confirmed yet whether air was rushing out or in while the gas cap was being removed...
