ABSTRACT:
An automotive type fuel tank has a fuel fill pipe with automatic pressure responsive fuel shutoff means, and a vapor vent assembly. The assembly has a small tube extending down through the top of the tank to below the normal fuel level of a full tank. The lower end is upturned and extends upwardly to a point near the top of the tank with a large orifice opening to vent vapors freely therethrough through the tube. A small orifice is drilled in the bottom of the tube at the bend to slowly bleed fuel into the tube as the tank fills until the fuel level blocks the vent of fuel vapors, resulting in a shutoff of the fill fuel. During operations other than filling, the small orifice prevents/minimizes expulsion of liquid fuel out the vent tube. A weighted ball further seals against fuel leakage upon vehicle or tank rollover.
