With the conversion to end feed injectors the fuel rail also need to be replaced. I used the Aeroflow billet fuel rail. This fuel rail does not require a manifold spacer, it comes with an ACV spacer which allows for the removal of the solid intake line that feeds the factory Idle Air Control Valve and the AC Idle up valve.
Note: This fuel rail comes with 3 aluminium spacers which I will be replacing with Phenolic Resin spacers to reduce the heat transfer from the manifold into the fuel rail.
