This patent describes a fuel delivery system for an internal combustion engine that includes a fuel supply with a pump responsive to application of electrical power for delivering fuel under pressure, an engine air intake manifold, fuel delivery means coupled to the fuel supply for controlled delivery of fuel from the supply to the manifold, pressure regulator means having a first input responsive to fuel pressure at the fuel delivery means, a reference input connected to the air intake manifold and an outlet connected through a fuel return to the supply. The regulator means are responsive to a predetermined pressure differentials across the fuel delivery means for passing excess fuel through the return to the supply, and means for applying electrical power to the pump.
