ABSTRACT:
An apparatus is provided for controlling flow of fuel vapor and liquid fuel through an aperture in a fuel tank. The apparatus includes a housing mounted in the aperture and a vent valve movable in the housing to block flow of fuel vapor between the fuel tank and an outlet. The housing is further formed to include a float valve movable between a closed position blocking flow of fuel vapor and liquid fuel through the outlet and an open position allowing flow of fuel vapor through the outlet. The float valve includes a wide-diameter base, an upwardly extending closure appended to the base member, and a downwardly extending narrow-diameter weighted unit depending from the base. The base and the weighted unit are sized, shaped, weighted, and located to cause the float valve to "snap" (e.g. move quickly and suddenly) to its closed position after rising fuel in the fuel tank rises past the weighted unit and engages the underside of the base.
