INSTALLATION INSTRUCTIONS
CAUTION:
Installation of this product requires detailed knowledge of automotive
systems and repair procedures. We recommend that this installation be carried
out by a qualified automotive technician.
Installation of this product requires handling of gasoline. Ensure you are
working in a well ventilated area with an approved fire extinguisher nearby.
Extinguish all open flames, prohibit smoking and eliminate all sources of ignition
in the area of the vehicle before proceeding with the installation.
When installing this product, wear eye goggles and other safety apparel as
needed to protect yourself from debris and sprayed gasoline.
WARNING!
The fuel system is under pressure. Do not open the fuel system until the
pressure has been relieved. Refer to the appropriate vehicle service manual for
the procedure and precautions for relieving the fuel system pressure.
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.
The enclosed Aeromotive fuel rails are intended to be installed on an unmodified OEM intake
manifold of the identified application. Aeromotive cannot guarantee the proper fitment on
aftermarket intake manifolds and the end user is responsible for verifying proper fitment and
assumes all liability.
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.
Aeromotive system components are not legal for sale or use on emission controlled motor vehicles.

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. Remove the air intake ducting.
3. 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.
4. Disconnect the electrical connector at each injector, making note of the location of each.
5. Disconnect both the supply and return 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.
Failure to satisfy all safety considerations will result in fire, explosion, injury and/or loss of
life to yourself and/or others.
6. Label and disconnect any electrical wiring, vacuum lines and throttle body components that will
interfere with the fuel rail removal and installation.
7. Remove the 4 mounting bolts that attach the 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 amount of gasoline.
Failure to satisfy all safety considerations will result in fire, explosion, injury and/or loss of
life to yourself and/or others.
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 parts store or
dealer to purchase the correct replacement o-rings.
11. Carefully install the new injector o-rings on the injectors.
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.
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

12. Place a thin coat of light oil in the fuel rail injector bores and in the lower intake manifold
injector bores to help prevent cutting the o-rings during installation.
13. Carefully place each of the fuel injectors in the corresponding fuel injector bore of the
Aeromotive fuel rails.
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.
The back side of the fuel rails may contact a factory fuel rail protection bracket attached to
the back lower intake. This bracket may require modification for extra clearance or
removal, please assess the risks in making these modifications. The end user assumes all
risks and liability related to the modification and/or removal of these OEM brackets
15. Reinstall the rail mounting bolts and tighten.
16. With the Aeromotive fuel rail properly secured to the intake manifold, Move the fuel injector
vertically downward until it bottoms out on the intake manifold, In this downward position,
inspect the upper fuel injector o-ring (on the fuel rail side) and insure it is fully covered by the
fuel rail injector bore. If any of the o-ring is exposed, loosen the fuel rail bracket screws and
adjust the installation height until the o-ring is no longer exposed and retighten the bracket
screws. In the situation where the fuel injector has no vertical travel, either the fuel rail brackets
can be adjusted or the brackets shimmed until the fuel injector fits freely. Do not pressurize the
fuel rail until the proper fuel rail installation height is achieved.
1. Install the appropriate port fittings and o-rings in each end of the fuel rail, we recommend
Aeromotive p/n 15605 for AN-06 fuel line connections or Aeromotive 15607 for AN-08.
2. Using an after-market fuel pressure regulator, we recommend Aeromotive p/n 13101, 13109 or
13129, in conjunction with AN style high pressure fuel lines and fittings, plumb the remainder of
the fuel system.

Ensure the any spilled gasoline and any gasoline soaked shop towels are cleaned up and removed
from the vicinity of the vehicle!
19. Reinstall any electrical wiring, vacuum lines, fuel lines, and throttle body components that were
removed during the original fuel rail removal.
20. 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
position, wait one minute, return the ignition to the ON position, and recheck the fuel pressure.
Repeat this ignition OFF and ON procedure until the fuel pressure gauge registers fuel pressure.
21. With the fuel pressure gauge registering fuel system pressure, check for fuel leaks from and
around all the fuel system components and all fuel lines and connections! If any fuel leaks are
found, turn the ignition key to the OFF position, remove any spilled fuel and repair the leak
before proceeding!
22. Once the fuel pressure gauge registers fuel system pressure and there are no fuel leaks, start the
engine and adjust the regulator to the desired fuel pressure.
23. Once the desired fuel pressure is achieved, tighten the regulator adjustment jam nut and attach the
vacuum line.
24. Turn off the engine and allow it to cool.
25. Test drive the car to insure proper operation and re-check the fuel system for leaks. If any leaks are
found, immediately shutoff the engine and repair the leak(s)!
