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. Note that in 1987 there were both 6.9 and 7.3 engines going into trucks. Be sure you know what you have.
