The DDP LB7 Injector Line Set covers the complete engine of your 2001-2004 GM 6.6L Duramax LB7 engine. It's highly recommended that you change your lines any time when replacing your injectors. On older lines, corrosion tends to build up on the lines resulting in debris that can be transferred into your new set of injectors. This is why we suggest changing the lines out with a new set any time you are under the hood and have the slight chance of getting any debris in there.
