Description
Replace your failed CP4 injection pump in your 2011-2016 GM 6.6L Duramax with this remanufactured replacement pump from BOSCH. This pump is a direct replacement and is designed to meet or exceed factory specifications.
Remanufactured does not mean “used” or “rebuilt”. It means that the part has been manufactured again. 100% of all parts are examined and the non-wearable parts are re-used. However, if there are any flaws, the part is discarded. The high pressure pump is rebuilt and all wearable components are replaced. The part is then tested before completion. The extent of the remanufacturing and testing process depends on the manufacturer.
