ABSTRACT:
A cap for closing the filler neck of a vehicle is provided. The cap includes a valve body and a vent adapted to allow a maximum amount of fuel vapor to vent to the atmosphere. The cap also includes a ball disposed within the valve body to seal the vent when the vehicle is rolled over to a substantially inverted position to prevent fuel from leaking from the cap. The cap further includes a baffle to prevent fuel from splashing through the vent when the vehicle is operated on a rough and uneven surface.
