Shop Blessed Performance for the XDP Fuel Contamination Kit for your 2011-2016 GM 6.6L LML Duramax diesel. When the CP4 fuel injection pump fails in your Chevy/GMC, it often sends contaminants through the entire fuel system. This results in debris from the pump that can contaminate the fuel lines, fuel injector lines, and fuel rails, meaning you now have to replace all of the aforementioned parts. Simply flushing the fuel system doesn’t guarantee all the residual metal shavings or contaminants will be removed. This CP4 failure kit is a complete repair solution for your 6.6 Duramax engine with CP4 fuel pump failure, DEF contamination, or water-in-fuel contamination.

This XDP Fuel Contamination Kit is built around a high-quality remanufactured CP4 pump and remanufactured stock replacement fuel injectors. This kit also includes a complete set of new fuel injector lines, feed pipe, return line, fuel rails, and a set of injector hold down bolts. Replacing these components will help ensure that all pump fragments are out of the fuel system, so you can be sure that the replacement fuel injectors and CP4 pump don't get contaminated from the previous pump failure.
