LB7 High Pressure Injection Line (3 and 6) For 01-04 Duramax LB7 Fleece
Original LB7 Injection lines will corrode and break and are a leading cause of contamination when changing the injectors. If you are changing your injectors, have a line failure, or are looking to upgrade your stock lines, we've got you covered with our direct replacement LB7 injection lines!
An upgrade to the factory lines on your 2001-2004 Duramax LB7, our Fleece Performance lines feature machined 4140 injector swivel nuts and are corrosion resistant.
