Installation tips and routing options

This item is for the early style kit originally found on the 6.9L engines. It includes 5mm / 3/16" hose, injector caps, and clamps and utilizes the centered nipple style injector caps that don't have an offset like the 7.3L. This kit can also be used on a 7.3L IDI if you would rather use the smaller hose and centered nipples.  Some minor adaptation at the fuel filter head bleeder fitting and return manifold would be needed on a 7.3L IDI.

We sell stock (I.E. "standard") kits as well.
