The Factory CP4.2 Pump Found 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 is no Longer Under Warranty we strongly recommend replacing the pump with a more robust CP3 pump. 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 2011-2015 Duramax's and are IN STOCK ready to ship same day.
**Kit only NO PUMP! EGR Must be deleted!
