2001-2004 Duramax Injector Line Set (412501)

Industrial Injection complete injector line set for 2001-2004 Chevrolet Silverado 2500HD/3500 and GMC Sierra 2500HD/3500 6.6L LB7 Duramax. Brand-new high-pressure fuel lines that should go on with any new or remanufactured injector install.

The single most common reason new LB7 injectors fail right after install is contamination from old lines that were never cleaned or were full of debris from a prior failure. Fresh lines remove that variable. Cheap insurance on an expensive job.
