Abstract

The fuel delivery system is designed, so that between the tank (16) and the fuel pump (12) an electric auxiliary pump (18) is positioned, which is arranged parallel to a non-return valve (22) in a Bypass line (20) of the pressure line system (14). The auxiliary pump and the fuel pump is assigned a control unit (24), across which a regulation of the conveying power of the auxiliary pump, results depending on a conveying power of the fuel pump.
