DHD's Deluxe LB7 Low Pressure Fuel Hose Kit includes all engine related fuel supply and return hoses for 2001-2004 LB7 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.
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.
