Kit Details

The 2017-2023 L5P Duramax engine, while a huge improvement in design over the prior generation Duramax, is not immune to failure which can occur when DEF or another foreign substance is added to the fuel system. This kit provides a complete repair solution for DEF contamination or water-in-fuel contamination on your 2017-2023 L5P Duramax This kit is comprised of 100% new OE parts with no remanufactured components. Simply flushing the fuel system is inadequate, and could lead to residual contaminants in your fuel system.  Contamination is the number one cause of repeat injector failure. Replacing all of the fuel system components is the only way to prevent recurring contamination issues.

Each component carries a three-year warranty. Information about warranty policies can be found HERE.
