Abstract: A vapor recovery fuel system includes a fuel tank having at least one vent opening defined therein. A fuel vapor canister is in communication with the vent opening to receive and filter fuel vapors from the tank. A refueling control valve is configured in the vent opening and has a first inlet orifice and an outlet in communication with the vapor trap. The control valve includes a variably buoyant first float body extending into an interior of the fuel tank which rises over a predetermined range of movement in response to increasing fuel level. The control valve includes a second float body engaged by the first float body over at least a portion of its range of movement. The first float body has a buoyancy during refueling so as to rise with increasing fuel level to engage and move the second float body into a sealing position to seal the inlet orifice from the outlet at a predetermined height of fuel within the tank.

Abstract: A fastening arrangement for a fuel injector including a retaining clip is disclosed which secures the injector to a fuel rail in a manner so that the injector cannot rotate relative to the rail. The clip has flexible arms defining an opening which is adapted to receive a portion of the fuel injector thereby locking the fastener and the fuel injector together. The clip also has a pair of opposed walls with elongated slot openings therein positioned to snap over an edge of a receiving nipple of the rail structure thereby securing the fastener and the rail together. The clip includes a pair of arms extending into overlying engagement with the fuel rail to prevent rotation of the clip and attached fuel injector relative to the rail.
