This item is for the late style kit originally found on the late 7.3L engines. It includes 7mm / 1/4" hose, injector caps, and clamps and utilizes the offset style injector caps. This kit can also be used in place of the early style 5mm / 3/16" kit for the 6.9L with minor adapting if desired.
We also sell stock (I.E. "standard") 6.9 and advanced 6.9 kit and 7.3 return kits.
Does not fit the Powerstroke/T444E direct injected engine that replaced the idi in 1994. We have seal kits for those injectors.
