Bring the fuel system on your 2020-2022 Chevy Silverado 1500 / GMC Sierra 1500 3.0L Duramax LM2 back from a contamination event in one coordinated repair with the Alliant Power Fuel System Contamination Kit. When DEF, water, gasoline or debris goes through the high-pressure pump, it sends metal through the rails, lines and injectors - this kit replaces all of it together to reduce the risk of repeat damage.
Inside the box is Fuel Injection Pump Kit AP55216, Fuel Injector Kits Cyl 1, 2, 4 - AP55129, Fuel Injector Kits Cyl 3, 5, 6 - AP55130, Fuel Cooler Assembly OE-eq 84740502, Fuel Rail with Pressure Sensor and Relief Valve OE-eq 55505909, In-Tank Fuel Pump OE-eq 86507850, Fuel Filter Assembly OE-eq 13543066, Fuel Return Line OE-eq 55515929, EGR Pipe Gasket OE-eq 55497083 and Seal OE-eq 55496593. Each fuel component is genuine OE or OE-equivalent and end-of-line tested at 15 points, and the kit is assembled in an ISO 9001:2015 certified facility. Alliant Power backs it with a two-year, unlimited-mileage warranty. A $750 core charge is collected at checkout and refunded once the rebuildable core is returned.
