Aeromotive 14134 - 04-06 SUBARU 2.0L WRX FUEL RAIL KIT - Manual (Page 3)

15. Coat the new fuel injector o-rings with a light oil to ease installation.
16. Carefully install the new injector o-rings on the injectors.
17. Install the appropriate union fittings, adapters and o-rings (not included) in each end of
the fuel rails. To prevent poor flow to the fuel injectors the use of cutoff or o-ring boss
style union fittings is recommended. In order to preserve the factory “fuel pipe
protectors” the following fitting configuration is recommended. The backside of each fuel
rail we recommend using a banjo fitting, Aeromotive p/n 15636 for AN-06 lines. The
front of the fuel rail on the right side (passenger) of the motor, we recommend using an
AN-08 90-degree Male ORB hose end, Aeromotive p/n 15665. The front side of the fuel
rail on the left side (Driver) of the motor, we recommend an AN-08 cutoff or o-ring boss
union fitting, Aeromotive p/n 15607. The fuel will be supplied to each rail via the AN-08
fittings and exit the rail through the two AN-06 Banjo Fittings to the fuel pressure
regulator.
18. Place a thin coat of light oil in the fuel rail injector bores to help prevent cutting the o-
rings during installation.
19. Carefully place each of the fuel injectors in the corresponding fuel injector bore of the
Aeromotive fuel rails.
20. Place each of the Aeromotive fuel rail / injector assemblies onto each of the tumbler
valves, being sure to align the bottom of each injector with the injector bores in the
tumbler valve.
21. Reinstall the fuel rail mounting bolts and tighten.
22. Orientate the fuel injectors such that the electrical connector is aligned with the outer
ends of the Aeromotive fuel rail.
23. It will be necessary to trim the alignment tabs off of the fuel injector wiring harness
connectors.
