2001-2004 Duramax Stainless Steel High Pressure Injector Lines (Set Of 8) (DMAX720123)

A complete set of eight ferritic stainless steel high pressure injector lines for 2001-2004 LB7 Duramax trucks, fitting Chevy Silverado and GMC Sierra 2500HD/3500HD. The ferritic stainless construction resists the corrosion the OE lines are prone to, and this set installs as a direct upgrade to the factory lines. Replacing the high pressure lines when you put in new injectors helps protect the injectors and prevent future leaks.
