The common rail pressure regulator valve controls fuel pressure within a diesel injection system. It works as a control component in the rail assembly, helping the system maintain the pressure required for fuel delivery under changing engine operating conditions.
It is used during fuel system repair when the existing pressure control valve requires replacement. Confirm the original reference, electrical connection and rail configuration before selecting the part. Installation should follow the vehicle manufacturer's procedure for the high pressure fuel system.

This fuel rail pressure regulator controls fuel pressure within a diesel common rail injection system. The component is installed on the fuel rail and is also catalogued as a pressure relief valve. It serves as a separate regulating component within the high-pressure fuel circuit, distinct from the injection pump and rail pressure sensor.
The valve works with the fuel injection control system to regulate the pressure available in the rail during engine operation. Its catalogued service position is identified as the second fuel pressure regulator. Reference information for the valve is listed separately from complete rail assemblies and pump-mounted metering components, which have different part numbers and installation positions.

The fuel pressure control valve is an electronic control component in modern diesel common rail fuel systems. Installed on the high-pressure fuel pump or fuel-pressure circuit, it regulates the pressure supplied to the rail in response to commands from the engine control unit. By controlling fuel flow and pressure, it supports stable common rail operation and accurate fuel delivery.
This replacement valve is listed for selected 2.8 L diesel applications from Fiat, Iveco, Citroen, Peugeot and Renault. It is intended for service and repair of common rail fuel systems. Equivalent numbers, vehicle applications and applicable pump references are listed below.
