Section 2 – Fuel Rail Installation
2-1. Check for any dirt or debris around the fuel injectors. If any is evident, wash it off with some solvent parts cleaner or
wipe it off with a clean shop towel.
2-2. Disconnect the electrical connector at each injector, making note of the location of each.
2-3. Disconnect both the supply and return (If applicable) fuel lines from the OEM fuel rails. These lines are attached by a
special quick disconnect fitting which requires a special tool for removal. Place clean shop towels around the open
fuel lines to catch any gasoline that may drip out and to prevent any dirt from entering the fuel lines.
2-4. Remove the air intake tube.
2-5. Label and disconnect any electrical wiring, vacuum lines and throttle body components that will interfere with the fuel
rail removal and installation.
2-6. Remove the 4 mounting bolts that attach the fuel rail to the intake manifold.
2-7. Place clean shop towels around the injectors to catch any gasoline that may be spilled during their removal. Remove
the injectors from the manifold by gently pulling upward on the fuel rail / injector assembly. Keep all injectors
connected to the fuel rails. If an injector does pull out of the fuel rail, it may spill a large amount of fuel.
2-8. Carefully remove the fuel injectors from the fuel rail.
2-9. Remove the old o-rings from the fuel injectors, inspect the injectors for any dirt or debris and clean if needed. It is
suggested that the old o-rings be replaced, contact your local auto parts store for replacement o-rings.
2-10. Coat the new fuel injector o-rings with a light oil or petroleum jelly to ease installation.
2-11. Carefully install the new fuel injector o-rings on the injectors.
2-12. Place a thin coat of light oil or petroleum jelly in the fuel rail fuel injector bores and in the lower intake manifold
injector bores to help prevent cutting the o-rings during installation.
2-13. Carefully place the each of the fuel injectors in the corresponding fuel injector bore of the Aeromotive fuel rails.
Position the electrical connector on each fuel injector to the opposite side of the fuel rail as the mounting bracket.
2-14. Place each of the fuel rail / injector assemblies onto the lower intake manifold, ease the fuel injectors into the
injector bores in the lower intake being careful that the injector does not dislodge itself from the fuel rail.
2-15. Reinstall the fuel rail mounting bolts and tighten.
2-16. Reinstall any electrical wiring, vacuum lines, and throttle body components that where removed for the original fuel
rail removal.
