Abstract

A fuel supply system for an internal combustion engine in which a fuel pump pumps fuel from a fuel tank to a fuel distributor and a pressure regulator is connected between the fuel pump and the fuel distributor to respond to pressure of the fuel pumped by the fuel pump, to return fuel back to the fuel tank as a function of the pressure of the pumped fuel, a pressure reducer being disposed between the pressure regulator and the fuel distributor to reduce the pressure of the fuel delivered to the fuel distributor to a value lower than the pressure of the fuel at the pressure regulator.
