ABSTRACT:
For supplying fuel from a fuel tank to an internal combustion engine by a fuel supply pump, a fuel delivery pressure of the fuel supply pump is regulated by a pressure regulating valve so as to maintain the difference between the fuel delivery pressure of the pump and an inner pressure of an intake manifold of the engine at a prescribed constant value, and the delivery volume of fuel from the pump is controlled in response to the fuel delivery pressure so as to minimize the amount of surplus fuel produced by the pressure regulating operation of the pressure regulating valve.
