Fuel Pressure Regulator

The pressure regulator is a diaphragm-operated relief valve with injector pressure acting on one side and atmospheric pressure acting on the other. The pressure regulator maintains a constant pressure drop of about 10 psi (.7 kg/cm2 ) across injector(s), throughout all engine operating conditions. The model 700 fuel pressure regulator may be disassembled and repaired.
