INSTALLATION INSTRUCTIONS

The following steps are typical of most installations

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.
Remove the air intake ducting from the throttle body and position it out of the way.
Note the location of and remove any vacuum lines connected to the upper intake manifold and position them out of the way.
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.
Disconnect the electrical connector at each injector, making note of the location of each.
Carefully relieve fuel system pressure per factory service manual.
Disconnect the supply fuel line from the OEM fuel rails. This line is 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.
Remove the vacuum line from the fuel pressure sensor.
Remove the bolts that attach the fuel rail to the lower intake (Typically there are 4 of them).
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.
Carefully remove the fuel injectors from the OEM fuel rail.
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.
Coat the new fuel injector o-rings with a light oil to ease installation.
Carefully install the new fuel injector o-rings on the injectors.
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.
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.
Install the driver side fuel rail, being careful not to cut any of the o-rings during Installation.
Install the passenger side fuel rail, being careful not to cut any of the o-rings during installation.
Find suitable place in the vehicle’s engine compartment to place the Aeromotive fuel sensor adapter, typically just behind the alternator.
Install one AN-08 o-ring on each of the six AN-8 cutoff tapered flare fittings.
Thread the side of the AN-8 cutoff tapered fitting with the o-ring into each of the two AN-8 ports on the fuel pressure sensor adapter.
Thread the o-ring side of each four AN-08 cutoff tapered flare fittings in each end of the fuel rail.

Connect one AN-08 90-degree hose end to each of the two ports on the front end of the fuel rail. Connect one AN-08 45-degree hose end to the passenger side of the fuel pressure sensor adapter. Connect one AN-08 straight hose end to the driver side of the fuel pressure sensor adapter. Plan a route for each of the two lines between the fuel pressure sensor adapter and the fuel rails, measure the two lengths of fuel line needed. See section titled Hose and Fitting Assembly for fuel line assembly instructions. Once the hoses are assembled, ensure there is no debris in the hose and install them.
Inspect the OEM fuel supply line o-rings and replace if necessary. Place a light coat of oil on the fuel supply line o-rings and the supply line adapter fitting to ease installation. Connect the AN-08 tee adapter fitting to the OEM fuel supply line.
Using the remaining AN-08 hose end fittings as a guide, measure the required fuel line lengths needed and make up the last two required AN-08 fuel supply lines (See section titled Hose and Fitting Assembly). A typical configuration is pictured below.

Reassemble the vehicle using the reverse of the foregoing removal procedure.
When installing the fuel pressure sensor in the Aeromotive fuel sensor adapter block, it may be necessary to bleed any trapped air from around the sensor. Failure to do so could result in random hesitations and/or ill performance.
Remove the 1/8 NPT pipe plug from the fuel supply adapter tee fitting and attach a suitable fuel pressure gauge if desired.
Ensure that any spilled gasoline and any gasoline soaked shop towels are cleaned up and removed from the vicinity of the vehicle!
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.
With the fuel pressure gauge registering fuel system pressure, check for fuel leaks from and around the Aeromotive fuel pressure sensor adapter, fuel rails, 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!
Once the fuel pressure gauge registers fuel system pressure and there are no fuel leaks, start the engine.
Turn off the engine and allow it to cool. If you do not want to keep the fuel pressure gauge on the vehicle, relieve the fuel system pressure as instructed in the appropriate vehicle service manual. Remove the fuel pressure gauge and reinstall the 1/8 NPT pipe plug, using thread sealant.
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)!

Hose and Fitting Assembly

CAUTION:
When assembling this product, wear eye goggles and other safety apparel as needed to protect yourself from debris and sharp edges.

A. Wrap hose with masking tape at desired cutoff length. Cut hose through masking tape squarely to desired length using a cut-off machine or a fine tooth hacksaw. Remove the masking tape.
B. Unthread the hose socket from the rest of the hose end fitting.
C. Insert hose in the socket with a twisting and pushing motion until the hose is fully seated in the socket.
D. Using a grease pencil, marker or tape, mark the location of the hose in relation to the hose socket which you just installed.
E. Using a light oil lubricate the inside of the hose and the hose end mating parts.
F. Carefully thread the hose end onto the hose socket, making sure that the hose does not push out of socket, by observing the mark you placed on the hose in step D.

G. Using a properly sized wrench, complete threading the two components together (The maximum allowable gap between the two fitting components is .030 inches).
H. Inspect the hose for push out by comparing the mark you made on the hose in step D to the hose end socket location.
I. Clean all debris from exterior and interior of hose.
J. All lines should be tested to twice their operation pressure prior to use.
