LGH Duramax CP4 Fuel Contamination Kit | 0445117008, 0445010817 | 2011-2016 Chevy / GMC Duramax LGH

This is your complete repair & replacement solution for your CP4 system with fuel pump failure or DEF contamination, featuring new injectors and pump for the Duramax LGH. Simply flushing the fuel system is inadequate and could lead to leftover contaminants in your fuel system. Replacing all of the fuel system components is the only way to prevent recurring contamination issues, since contamination is the number one cause of repeat injector failure. If you've been going through injectors, this is the kit for you!

This kit can be bought with or without the CP4 pump, please select from the drop down before checking out.

Kit Includes:

• BOSCH® OEM New LGH Injectors (8)
• BOSCH® OEM New CP4 Pump (Updated)
• BOSCH® OEM New Fuel Rails (2)
• BOSCH® OEM New Return Line Assembly
• GM OEM New Fuel Lines (Pump to rail, rail to rail & rails to injectors)
