  • Patent number: 4945884
    Abstract: A canister with an electric fuel pump therein is connected to a cover for an access port through which the canister is installed on a fuel tank of an automobile by three hollow struts. Each strut has a first end press fitted into a socket on the cover and is telescopically received in a bore in the canister. Coil springs around each strut urge relative separation between the strut and the cover and a flare at a second end of each strut defines a stop to limit relative separation. A passage in the cover from a return fuel connection on an exposed side of the cover to one of the sockets conducts low pressure return fuel to the one of the hollow struts press fitted therein. The return fuel flows back to the canister through the one hollow strut.

  • Patent number: 4718827
    Abstract: An improvement in automotive fuel pump assemblies of the type including a tubular cylindrical housing, an electric motor in the housing and a pump in the housing driven by the armature of the motor. The pump includes a first pump body adjacent a flux ring of the motor, a second pump body between the first pump body and the end of the tubular housing, and an impeller in a cavity between the pump bodies. The improvement resides in the provision of axially extending grooves in outer cylindrical surfaces of the pump bodies which register in only a single predetermined angular positional relationship of the pump bodies and in the provision of spring clips which fit in the registered grooves to maintain the predetermined positional relationship and to unitize the pump bodies for efficient handling prior to insertion in the tubular housing.
