The XDP OER Series Fuel Injector Line (Cylinders 4 and 5) XD596 provide your 2001-2004 GM 6.6L Duramax LB7 with high-quality fuel lines. As time passes, factory injector lines can corrode and become a point of failure. Also, in order to avoid the risk of contamination, it is advisable to replace the fuel lines when replacing your fuel injectors.

XDP high-pressure fuel lines are OE-style replacements that match the fit and function of your Duramax's stock lines. Unlike other options, XDP lines are brand new and not remanufactured. Each line is built from only the highest quality materials to ensure the durability and dependability that your LB7 Duramax fuel system requires.
