A feedback control method for a fuel delivery system of an internal combustion engine, having a fuel delivery pump for supplying fuel, the fuel delivery pump having a pump mechanism driven by an electric motor, which is controlled by a generated control signal. The current fuel volume delivered by the fuel delivery pump and the prevailing fuel requirement of the internal combustion engine are included in the control signal. The prevailing fuel requirement is determined using characteristic variables that characterize the operating state of the internal combustion engine.
