# Fleece Performance 01-04 GM 2500/3500 Duramax LB7 Fuel Injection Line (1 & 8)

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.
