tell me does the gas cap vent to pressure or does it open under a vacuum? i say vacuum because what is the point of having it a sealed system. a buddy says it vents when there is too much pressure like when your driving and the gas sloshes around and start to build pressure so it will not blow the tank and such. so is it a pressure cap or a vacuum cap. thanks bp.
