Abstract
A filler neck cap includes a vacuum-relief valve member that moves from a normally closed position to an opened position when exposed to certain vacuum conditions to open a vent aperture and allow atmosphere to flow therethrough. The filler neck cap also includes a pressure-relief valve member formed to include the vent aperture that is closed normally by the vacuum-relief valve member.
