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 7.3 kits as well as an advanced 6.9 kit.
Does not fit the Powerstroke/T444E direct injected engine that replaced the idi in 1994. We have seal kits for those injectors.
