01-04 GM 6.6L LB7 Duramax XDP Fuel Injector Line (Cylinders 1 & 8)

Replace the contaminated or corroded fuel lines on your 2001-2004 GM 6.6L Duramax LB7 with the XDP OER Series Fuel Injector Line (Cylinders 1 and 8) XD594. The factory fuel injector lines can be a common point of failure as the lines often corrode over time and need to be replaced.

Additionally, if you are replacing the fuel injectors on your vehicle, the injector lines should also be replaced in order to prevent the risk of contaminating the new components. These high-pressure lines are OE-style replacements that match the fit and function of the original components on your LB7 Duramax engine.

Each line is constructed from high-quality materials and is built to deliver the durability and dependability your Duramax fuel system needs.
