Product Description

LML CP3 Conversion Kit

The factory High Pressure CP4.2 Pump on 2011 and newer Duramax’s has been known to be a problematic component. Fuel or water contamination can ruin the pumps internals very quickly leading to metal debris through the entire fuel system. When these pumps fail it can lead to very costly repair jobs usually including all new Injectors, Sensors, and full cleaning of the fuel tank and all fuel lines. Any truck that is used in a performance application and or no longer under warranty we strongly recommend replacing the pump with the more robust CP3 pump, used on older generation Duramax’s. This is the installation kit only, including all components to remove the CP4.2 and Install a CP3. Pumps are available separately. This kit fits 2011-2016 Duramax’s and are IN STOCK ready to ship same day.

WCFab offered one of the first CP3 Conversion kits to the market several years ago. Because of this, and several hundred kits being sold since its introduction, we have been able to improve our product thru customer feedback and R&D which offers the best overall fitting, and most complete kit on the market.

Note: This kit is for Competition Use only, the EGR must be removed.
