The enclosed Aeromotive fuel rails utilize o-ring sealed AN-08 style ports; these ports are NOT
PIPE THREAD and utilize NO THREAD SEALANT. To use the enclosed fuel rails in your vehicle’s
fuel system you must install the necessary adapter fittings and o-rings, high pressure fuel lines
and regulator to adapt your system to the configuration and ports of these fuel rails. Please call
for a catalog of the complete line of quality Aeromotive products.

When installing o-rings it is important to place a small amount of light oil on both the o-ring and
the mating surface to ease installation and prevent damaging the o-ring.

The following installation instructions are for a typical installation, for specific year and model
installation instructions please refer to your vehicles service manual.

Note: Extra Brackets and Lower Adapter O-rings included in kit are for applications using older
EV6 style fuel injectors. These o-rings are not OEM replacements.

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 the supply and return fuel lines from the OEM fuel rails, referring to the

appropriate vehicle service manual for the necessary tools and procedure on doing so.

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.

that will interfere with the fuel rail removal and installation.

7. Remove the 4 mounting bolts that attach the OEM fuel rail to the intake manifold.

8. 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 mount of gasoline.

9. Carefully remove the fuel injectors from the OEM fuel rail by removing the factory

retaining clips.

10. 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.

11. Coat the new fuel injector o-rings with a light oil to ease installation.

12. Carefully install the new injector o-rings on the injectors.

Note: If you are replacing the OEM fuel injectors with the older EV6 style fuel injectors
the included adapter o-rings will be used in place of the OEM o-rings on the lower
(intake manifold) side of the fuel injector and use the provided taller brackets

13. Install the appropriate union fittings and o-rings in each end of the fuel rail, we

recommend Aeromotive p/n 15605 for AN-06 connections or Aeromotive 15607 for AN-
