NEW – Genuine OEM Bosch – 5.9L Dodge Cummins Injection Pressure Regulator FITS 2003 – 2007 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 part 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 MPROP 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. PLEASE READ. We value your patronage. If a delay occurs that is longer than would normally be considered commercially acceptable, we will attempt to contact you. Please take a moment to read it. Local auto parts stores will not pay your travel costs to return a part either. Applications We guarantee our parts to be as described by part number, picture, and verbiage. While we do our best, vehicle applications, however, simply cannot be guaranteed. In most cases, we do not generate application lists. It is the nature of the auto parts business that, in rare cases, a part will not be correct for a certain vehicle even though it “should” fit. This may occur because of errors on application lists, mid-year production changes, changes to the vehicle since it was built, the fact that a car was not built for the US market, etc. If a part does not fit your vehicle, this does not mean the part is not as described. Problems can be solved much more easily when civility is kept intact.
