ABSTRACT:
A control apparatus for an electric fuel pump of a motor vehicle having an internal combustion engine which receives operating fuel from the motor operated fuel pump includes a dc-dc converter connected between a power source and the fuel pump. The dc-dc converter provides power for driving the fuel pump and is responsive to a voltage demand signal for setting the voltage level of the power. In one embodiment of the invention, a voltage demand signal generator, which generates the voltage demand signal, is a zener diode for generating a fixed voltage level for the power independent of the voltage level of the storage battery. In a second embodiment, the voltage demand signal generator is a portion of an engine control circuit for generating a varying voltage level for the power which is dependent on the operating conditions of the internal combustion engine.
