6.7 Cummins Fuel Pressure Regulator | Bosch 1465ZS0054

Restore proper rail pressure on a 6.7 Cummins CP3 with a genuine Bosch fuel pressure regulator. Bosch 1465ZS0054 is the OEM-style Fuel Control Actuator (FCA), also called an MPROP or metering valve, that mounts on the CP3 high-pressure pump and controls how much fuel enters the pump. A worn or contaminated regulator can cause a loping idle, surge, hard start, or low-rail codes. This new Bosch unit replaces the failed actuator and is built to OEM fit, form, and function.
