Alliant AP63723 #2 and #7 Injection Line 01-04 6.6L GM Duramax LB7 ALI-AP63407 CROSS REFERENCE PART NUMBERS 4C3Z9F452AThe LB7 Duramax's are notorious for injector failure due to a design flaw of the original injectors. Further, it was very common that when these injectors failed, failure would soon occur immediately after, and it was determined that it was due to corrosion build up in the injector lines that simply needed to be replaced ANYTIME the injectors are replaced. This injector line is a direct replacement and will fit either cylinder hole #2 or #7. SOLD
