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.
