Abstract: A fuel pump includes an electric motor, a pump stage and a motor housing with a plastic section that holds a stator of the electric motor. The plastic section has a rim on the side facing the pump housing, when seen from the stator. A sheet metal sheath engages behind a rim of the motor housing and a rim of the pump housing by rolled portions so as to permit the fuel pump to be produced cost-effectively.

Abstract: A fuel pump, in which a connecting piece for a fuel line and electrical connecting lines are radially guided in a motor housing, includes an electric motor. The motor housing has a section made of plastic such that the fuel pump has reduced axial dimensions.
