10. Slightly coat the outside of both o-rings with grease to ease installation of the injectors to the head and
the rail.
11. Carefully insert the injector to the bungs on the head making sure the o-rings does not get kinked. Make
sure the injector plugs are facing toward the passenger side.
12. Re-install the factory fuel rail. Once the rail is on, tighten the bolts slightly with your finders. Do not
tighten the rail to the head yet; slightly twist the injectors back and forth to make sure all the injectors are
seated properly.
13. With all injector plugs facing the passenger side, plug the injector harness to the injectors.
14. Once all the injectors are plugged, slightly twist the injectors so all the injector plugs are facing toward the
rear of the vehicle. This will allow the injectors’ spray pattern to correctly match the factory spray pattern.
15. Tighten the two nuts that holds the rail to the head.
