This patent describes a fuel pressure regulator for an internal combustion engine, comprising a first diaphragm, a fuel pressure regulating chamber defined partially by the diaphragm, a valve seat provided in the fuel pressure regulating chamber. The valve seat having an overflow opening, a valve member fixedly mounted on the diaphragm and relatively moveable with respect to the valve seat, a first resilient member for biasing the valve seat to close the overflow opening thereof, a second resilient member adapted to provide an additional biasing force to the valve member to thereby increase fuel pressure in the fuel pressure regulating chamber when required, and a drive means responsive to an operation engine to selectively bring the second resilient member into operation.
