Restore the contaminated fuel system in your GM 6.6L Duramax L5P with the Merchant Automotive 25012 Fuel Contamination Kit. Designed as a comprehensive repair solution, this kit replaces the critical fuel system components affected by contamination from DEF, gasoline, metallic debris from a failed fuel pump, and other foreign material.

Fuel system contamination can spread throughout the high- and low-pressure sides of the system, potentially damaging the injection pump, injectors, fuel rails, lines, and related components. Replacing only the failed component can leave residual contamination behind and put new parts at risk. The Merchant Automotive 25012 provides the major components, seals, gaskets, O-rings, and hardware needed to perform a complete fuel system repair and help prevent repeat failures.
