The Duramax L5P engine, renowned for its power and efficiency, is unfortunately susceptible to fuel contamination. Whether it’s DEF fluid or water, contaminants can wreak havoc on your fuel system, leading to costly repairs. This comprehensive guide explores the L5p Contamination Kit, a comprehensive solution designed to restore your 2017-2023 L5P Duramax to peak performance.
Understanding the Need for an L5P Contamination Kit
Contamination in your L5P Duramax fuel system isn’t a minor issue; it’s a significant problem that demands a thorough solution. Simply flushing the system is often insufficient, as residual contaminants can linger and cause recurring issues, most notably injector failure. The L5P contamination kit offers a complete overhaul, replacing all critical fuel system components with new, OE parts, ensuring long-term reliability.
What’s Included in the L5P Contamination Kit?
This comprehensive kit includes every component necessary for a complete fuel system restoration:
- Genuine GM/Denso OE Injectors (8): Brand new, high-quality injectors that provide precise fuel delivery and optimal performance.
- Genuine GM/Denso OE HP4 Pump: A new high-pressure fuel pump, ensuring consistent fuel pressure and preventing future contamination issues. This pump includes a new fuel pressure regulator and the latest components from Denso.
- Genuine GM OE Fuel Rails (Driver & Passenger Side): These rails include the necessary sensors and valves for accurate fuel management (Rail Pressure Control Valve on driver side and Rail Pressure Sensor on passenger side).
- Genuine GM OE High Pressure Fuel Lines (8 pieces): These lines connect the injectors to the fuel rail, ensuring a leak-free, high-pressure fuel delivery system. There are two distinct line shapes, with four of each included to service all eight injectors.
- Genuine GM OE Fuel Return Lines (Driver & Passenger Side): Complete assemblies with hard lines, bolts, and gaskets for efficient fuel return.
- Genuine GM OE Low Pressure Fuel Supply Pipe Assembly: This assembly includes the low pressure lines, mounting brackets, and rubber hoses for a complete low-pressure fuel supply system.
- Genuine GM OE High Pressure Fuel Supply Lines (Pump to Rail & Rail to Rail): These crucial lines connect the high-pressure pump to the rail and the rails to each other, ensuring a robust high-pressure fuel supply.
- Genuine GM/AC Delco OE Fuel Filter: A new fuel filter to remove any remaining contaminants and protect the new fuel system components.
Why Choose an L5P Contamination Kit with Genuine OE Parts?
Opting for a kit with Genuine OE parts guarantees quality, reliability, and compatibility. These components are identical to those used in the factory assembly of your L5P Duramax, ensuring a perfect fit and optimal performance. Each component in the kit comes with a three-year, unlimited mileage warranty for peace of mind.
Core Return Requirement
Please note that the eight injectors and the high-pressure fuel pump require a core return. This process allows for the remanufacturing of used components, promoting sustainability and reducing waste.
Shipping Information
Due to the size and weight of the L5P contamination kit, standard shipping is typically ground. Expedited shipping options may be available at an additional cost.
