ABSTRACT:
The closure cap for fuel receptacle incorporates therein a liquid level gauge. The cap generally comprises annular hand grip means with a framing plate therein. The liquid level gauge includes an indicator shaft rotatable within an opening in the framing plate generally coaxial with the closure cap. The opening in the framing plate is in communication with the atmosphere and thus also serves to vent the receptacle when the cap is in closure position. Check valve means are carried on the shaft adjacent to and beneath the framing plate to normally close the opening and thereby prevent egress of sloshed fuel through the opening. The check valve means are adapted to open to vent the receptacle in response to a predetermined pressure differential across the valve means.
