If your 3.0L Duramax LZ0 has had fuel system contamination from DEF, gasoline, or debris, this Merchant Automotive Fuel Contamination Kit gives you the complete repair solution in one package. Contaminated fuel can damage everything it touches, so replacing only one or two parts can lead to repeat issues, poor drivability, or another costly failure down the road.
This kit includes the major fuel system components needed to restore the truck back to OEM standards, including the high-pressure fuel pump, fuel rail assembly, full injector set, fuel feed pipes, return pipe, seals, gaskets, water separator, and fuel filter. Instead of piecing parts together one by one, you get a complete direct-fit kit built specifically for the 3.0L LZ0 Duramax platform.
Backed by Merchant Automotive’s diesel experience, this kit is designed to help protect your investment, restore proper fuel system operation, and give you confidence that the repair was done the right way the first time!
