2001-2004 Duramax Fuel Injector Line Set (DDPLB7LINE-SETV2)

Protect your new injectors and ensure the integrity of your fuel system with the Dynomite Diesel LB7 Fuel Injector Line Set. On the 2001-2004 Duramax, factory lines are notorious for collecting corrosion and debris at the point where the line meets the injector. This rust can be pushed into the injector during installation or under high pressure, leading to premature failure. These corrosion-resistant replacement lines are a vital upgrade during any injector swap, providing a clean, reliable seal for your high-pressure fuel system.
