DHD Deluxe L5P Duramax Low Pressure Fuel Line Kit 2017-2023

DHD's Deluxe L5P Low Pressure Fuel Hose Kit includes all engine related fuel supply and return hoses for 2017-2023 L5P Duramax Diesel pickups. These molded hoses often crack and deteriorate over time leading to leaks and hard starting issues. If you find one hose is leaking its always best practice to replace the set.

Purchasing this kit will reduce downtime waiting for OE backorders and provide a cost effective solution to purchasing complete GM assemblies when all you need is a hose.

DHD fuel hoses are specifically engineered to match the exact fit and function as OE. DHD's exclusive 2 layer braided hose utilizes high quality Nitrile and Neoprene rubber to remain flexible, leak free and resist to UV and ozone deterioration for years. Unlike your original 20 year old OE hoses, our hoses are designed to work with todays modern low sulfur and bio fuels.
