2011-2016 GM LML 6.6L Duramax Bosch Fuel Pressure Relief Valve

OEM Bosch Fuel Rail Pressure Regulator Relief Valve

The high-pressure rail gives its name to the common-rail system and binds the fuel injection pump and the fuel injectors together as the central hydraulic component. The Common Rail system stores the high-pressure fuel and supplies this to the eight fuel injectors as needed. A rail pressure sensor and relief valve are independent parts of the common rail fuel injection system design. The 6.6L Duramax diesel engine uses a pressure regulator, pressure control valve, or pressure limiting valve which is located at the end of the high-pressure common rail.

The Bosch Diesel Fuel Injection Pump Pressure Relief Valve is one of the major components fitted on the high-pressure common rail. The RPS Sensor or rail pressure sensor is installed on the high-pressure to constantly monitor the output pressure of the fuel injection pump. The rail pressure sensor transmits this data back to the engine control module or ECM to optimize engine performance. The rail sensor communicates the pressure values serve to regulate the system pressure and controls the injectors. The pressure control valve sets the fuel injection system pressure supplied to the common rail injection system. The pressure regulator or limiting valve will reduce the common rail pressure in case of overload to protect the fuel injection system components injection from damage.
