LB7 Injector Cup Puller, Duramax | 2001-2004

The Merchant Automotive LB7 Injector Cup Puller removes the injector cup, also called the injector sleeve, from the cylinder head on 2001–2004 LB7 6.6L Duramax engines. LB7 injector cups commonly leak with age, letting coolant or combustion gases into the wrong places, and they have to come out cleanly to be resealed or replaced. This puller grips the cup and draws it straight out of the head without damaging the cup or the bore. That's a job that's slow and risky with improvised tools.
