2001-2004 GM 6.6 Duramax LB7 Injector & Return Line Seal Kit
When installing a Duramax injector, new seals and o-rings must be used. This kit includes new copper washers for the injector tip, new copper seals for the injector return lines, and new o-rings for the 2001 to early 2004 LB7 Duramax engines. One kit is enough for four injectors.
Two kits are needed for a complete engine.
