This is a CP3 high-pressure common-rail pump remanufactured by Bosch, Bosch 0986437333. It is the remanufactured version of new Bosch 0445020148 (earlier 0445020107 and 0445020072) and matches Cummins 5264250, 4994547, 4929594 and 4929471. It fits the Cummins ISB 6.7 midrange engine used in medium-duty trucks and buses, 2007 to 2010 model years. On this engine the CP3 is driven off the rear gear train.

Do not mix it up with its lookalikes. Ram 2500, 3500, 4500 and 5500 trucks from 2007.5 to 2018 are listed under Bosch 0986437334 (Mopar 68027022AC), and 2010 to 2016 midrange ISB 6.7 engines take Bosch 0986437370. Common reasons to replace a CP3 are low rail pressure codes, hard starting, loss of power under load, or metal in the fuel filters. Water or dirt in the fuel is the usual root cause, so fix that before the replacement pump goes on.

Specifications

Fits / Applications

• Cummins ISB 6.7 midrange, 2007 to 2010 model years, rear gear train
• Medium-duty trucks and buses powered by that engine (confirm by ESN and CPL)
• 2010 is a changeover year: 2010 to 2016 engines take 0986437370

Replace the fuel filters and check fuel supply to the pump before fitting. If the old pump left metal in the filters, clean the tank, lines and rail and check the injectors, or the debris will damage the new pump. Move the drive gear over from the old pump if the replacement comes without one, torque the gear nut to the Cummins spec, and prime the fuel system before cranking.
