This part is called by many names including:
MPROP
FCA
Injection Pressure Regulator
Fuel Pressure Regulator
Fuel Control Actuator
Measuring Unit

The function of the injector pressure regulator is to control the output pressure of the high pressure CP3 fuel pump. When the part fails, the actual fuel pressure will not match the desired fuel pressure as specified by the engine computer. Both pressures can be monitored on a scan tool and compared. The most common symptom as the part begins to fail is varying / unstable idle.

The 5.9 Cummins fuel pressure regulator is mounted on the back side of the CP3 pump and is attached by (3) T-25 Torx head screws. Two o-rings seal the MPROP to the pump and are included already installed on the new part.

Cummins Fuel Control Actuator replaces the following part numbers (and others):
