Finish off a fuel injector repair in your 2011-2016 Chevy/GMC 6.6L LML Duramax with new or remanufactured Fuel Injector Lines. Fuel Injector Lines carry fuel from the injection pump or high-pressure common rail (depending on the application) to the fuel injector. When repairing injectors due to fuel contamination, it is also recommended that you replace fuel injector lines to avoid contaminating your new fuel injectors. On some engines the fuel injector lines are considered a "one-time-use" component and need to be replaced when new fuel injectors are installed.
