Industrial Injection AP54820 L5P Fuel Contamination Disaster Kit

The Industrial Injection AP54820 L5P Fuel Contamination Kit provides a complete solution for repairing fuel system failures caused by contamination in 2017-2019 GM 6.6L Duramax L5P engines. When a CP4 injection pump fails, it sends metal debris throughout the entire fuel system, contaminating injectors, fuel rails, and lines. This comprehensive disaster kit includes all the components necessary to completely restore your fuel system to factory specifications.

Complete Kit Includes:

• 8 remanufactured fuel injectors with 100% new nozzles
• 1 remanufactured high-pressure injection pump
• 2 fuel rails (left and right)
• 8 injector hard lines
• 3 high-pressure fuel lines
• 1 fuel return line
• Installation hardware and seals

Key Features:

• Direct replacement for stock fuel system components
• Meets or exceeds all OEM specifications
• Remanufactured in ISO 9001:2015 certified facility in the USA
• All wear components replaced with OE or OE-equivalent parts
• 2-year unlimited mileage warranty
• Addresses most common cause of L5P fuel system failure

Important Fitment Note: This kit is designed for 2017-2019 L5P Duramax engines and includes the appropriate fuel cooler for those model years. For 2020+ applications, an additional fuel cooler (PN: 84740502) must be purchased separately due to GM's switch from air-to-fuel cooler to coolant-to-fuel cooler design.

Core Return Policy: Core charges apply to 8 injectors, 1 pump, and 2 fuel rails. All cores must be returned in original packaging to receive full core credit.
