ABSTRACT:
A refueling valve for a motor vehicle includes a body connected to the upper wall of a fuel tank in vertical depending relationship. The body has a cover with a vapor exit passage adapted to be connected to a fuel vapor storage canister and a portion depending from the cover that has a vapor exit port that communicates with the fuel tank interior adjacent the upper wall of the fuel tank. A vent tube has one end connected to the vapor exit passage and an opposite end that communicates with the vent exit port and defines a valve seat. The vapor exit port is located with respect to the valve seat so as to separate liquid fuel particles from vapor flow during fuel fill. The valve seat is closed by a float valve when the fuel tank is full.
