2001-2004 Duramax LB7 Fuel Return Line Banjo Bolt (AP0059)When it comes time to replace the injectors in your LB7, we highly recommend replacing the factory return line banjo bolts that need to be removed for the job. Many times, the factory bolts can become stripped during the disassembly process, and having a fresh, clean set on hand can avoid unnecessary down time in sourcing new ones. Banjo bolts are sold individually, increase quantity to eight for a complete kit.
