The Alliant 6.6L Duramax LB7 Injection Lines are a cost effective replacement for your 01-04 GM 6.6L Duramax LB7. Stock injector lines are prone to corrosion build up due to their through the valve cover design. When lines are removed during service, existing protocol requires cleaning the lines or replacing with new. Due to the high replacement cost of OEM lines, cleaning is often times the preferred method. With cleaning comes inherent risks such as damaging the mating surface of the line that seals to the injector as well as introducing damaging particles into the injector which can lead to failure. Alliant Power now offers these lines at a cost effective price point when compared to labor intensive and potentially damaging cleaning procedures as well as expensive lines through the OEM.
