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. Remove the air intake ducting from the throttle body and position it out of the way.

3. Note the location of and remove any vacuum lines connected to the upper intake manifold and

position them out of the way.

4. 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.

5. Disconnect the electrical connector at each injector, making note of the location of each.

6. Carefully relieve fuel system pressure per factory service manual.

7. 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.

8. Remove the vacuum line from the fuel pressure regulator.

9. Remove the bolts that attach the fuel rail to the lower intake (Typically there are 4 of them).

10. 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.

11. Carefully remove the fuel injectors from the OEM fuel rail.

12. 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 Ford parts dept.

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

14. Carefully install the new fuel injector o-rings on the injectors.

15. 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.

16. Carefully place the fuel injectors in the fuel rails (depending on vehicle, placing the injectors in the

intake first might ease installation). Position the electrical connector on each fuel injector to the
opposite side of the fuel rail as the mounting bracket.

17. Install the driver side fuel rail, being careful not to cut any of the o-rings during Installation. The driver

side fuel rail will have a wider bracket spacing than the passenger side.

18. Install the passenger side fuel rail, being careful not to cut any of the o-rings during installation.

19. Find suitable place in the vehicle’s engine compartment to mount the Aeromotive regulator, typically

on the driver side wiring harness cover. This is located above the driver side fuel rail. Using the

supplied mounting bracket as a template, mark the bracket mounting holes and drill to accept a #10
screw.

20. With the bracket attached to the regulator, mount the bracket and regulator to the vehicle using two

#10 screws, nuts and lock washers.

21. Install one AN-10 o-ring on each of the two AN-10/AN-8 cutoff tapered flare fittings and one o-ring on

the AN-06 union fitting.

22. Thread the side of the AN-10/AN-8 cutoff tapered fitting with the o-ring into each of the two AN-10

ports on the regulator. Also thread the AN-6 cutoff tapered flare into the bottom of the regulator.

23. Install one AN-08 o-ring on each of the four AN-08 cutoff tapered flare fittings.

24. Thread the o-ring side of each four AN-08 cutoff tapered flare fittings in the back of each fuel rail.

25. Inspect the o-rings on the OEM quick disconnect fitting and replace if necessary. Coat o-rings and

the adapter fitting with a light oil and install the AN-06 / Ford quick disconnect adapter fitting on the
OEM By-pass fuel line.

Please note if installing a high performance fuel pump, (Similar to Aeromotive P/N 111-01-BF)
the OEM return line will be too restrictive to handle the volume of fuel that these pumps are
capable of pumping. To prevent loosing lower pressure adjustablity of your regulator it will be
necessary to replace the OEM return line with a 3/8” ID (AN-06) return line in these cases.

26. This kit contains one AN-06 straight hose end which will connect to the OEM fuel line adapter fitting

and one AN-06 90 degree hose end, to connect to the AN-06 union on the bottom of the fuel pressure
regulator. With these fittings in place, measure the length of fuel line needed. See section titled Hose
