The XDP LB7 Fuel Injector Line (Cylinders 2 & 7) XD597 provides your 2001-2004 GM 6.6L Duramax L87 with a high-quality replacement. The factory injector lines are prone to failure due to corrosion or fuel contamination. It is also recommended that you change your lines during fuel injector replacement to avoid the risk of contaminating the new components. This OE-style replacement matches the fit and function of the stock lines on your LB7 Duramax. Each line is constructed from high-quality materials to provide you with the durability and dependability that your fuel system needs.
