The following steps are typical of most installations:
1. Once the engine has been allowed to cool, disconnect the negative battery cable and relieve fuel
system pressure, referring to the appropriate vehicle service manual for the procedure on doing so.
2. 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.
3. Disconnect the electrical connector at each injector, making note of the location of each.
4. Disconnect both the supply and return fuel lines from the OEM fuel rails. 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.
5. Remove the vacuum line from the OEM fuel pressure regulator.
6. Remove the mounting bolts that attach the fuel rails to the intake manifold.
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.
8. Carefully remove the fuel injectors from the OEM fuel rails.
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 parts store.
10. Coat the new fuel injector o-rings with a light oil to ease installation.
11. Carefully install the new fuel injector o-rings on the injectors.
12. Install the supplied 15636 AN-08 Banjo fitting and o-ring in the front of each Aeromotive Fuel Rail.
13. Install the appropriate union fitting and o-ring in the rear of each fuel rail, we recommend Aeromotive
p/n 15605 for AN-06 or Aeromotive 15607 for AN-08.
14. Place a thin coat of light oil in the fuel rail fuel injector bores and in the lower intake manifold injector
bores to help prevent cutting the o-rings during installation.
15. Carefully place each of the fuel injectors in the corresponding fuel injector bore of the Aeromotive fuel
rail.
16. After insuring that the injectors are properly seated in the intake manifold injector bores, reinstall the
fuel rail mounting bolts.
17. Using an after-market fuel pressure regulator (We recommend Aeromotive 13101, 13109 or 13105)
and high pressure fuel lines and fittings, plumb the remainder of the fuel system
Ensure that any spilled gasoline and any gasoline soaked shop towels are cleaned up and
removed from the vicinity of the vehicle!
18. Reconnect the battery and turn the ignition to the ON position WITHOUT starting the car. After
several seconds, check the fuel pressure. If there is no fuel pressure, turn the ignition key to the OFF
