The XDP OER Series Duramax 6.6L L5P Fuel Contamination Kit XD608 will replace all the debris-riddled parts in the fuel system of your 2017-2021 GM 6.6L Duramax L5P. When the HP4 fuel injection pump fails in your Duramax-powered truck, it often sends debris throughout the entire fuel system.

This results in contamination from the pump that can contaminate the fuel injector lines, fuel lines, and fuel rails, meaning you now must replace all of these parts. Simply flushing the fuel system doesn’t guarantee all the lingering metal shavings or contaminants will be eliminated.

This HP4 failure kit is a complete repair solution for your 6.6 Duramax engine with HP4 fuel pump failure, DEF contamination, or water contamination in the fuel system.

This XDP Fuel Contamination Kit XD608 is developed around a high-quality remanufactured HP4 pump and remanufactured stock replacement fuel injectors. This kit also includes a complete set of new fuel injector lines, fuel rails, fuel filter, O-rings, and gaskets.

Replacing these components will help ensure that all debris is out of the fuel system, so you can be sure that the new components don’t get contaminated from the previous pump failure.

  • Fuel Filter
  • Gaskets and O-Rings
  • (2) Fuel Rails
  • (8) Fuel Injector Lines

Note: The core charge on this contamination kit requires that the HP4 injection pump, all 8 injectors, and both fuel rails must be returned for full core credit.
