DTech Injector Line (cylinders 3 & 6) For 2001-2004 Gm 6.6L Duramax LB7 DT660032

Avoid injector contamination on your 2001-2004 GM 6.6L Duramax with the DTech DT660032 Injector Line. On the LB7 engine, the factory lines commonly corrode around the line and nut area. Re-using them when installing new injectors greatly increases the chance of injector contamination. New DTech lines save you time and money by reducing the possibility of contaminating your new injectors. This single line fits cylinder 3 or 6. Lines sold individually, 2 required for both cylinders.
