THE BACK

STEP 15 

Assemble the fuel pressure regulator mount and your choice of regulator using the 3 supplied 

screws and regulator- to- mount gasket.

STEP 16

 Place one of the supplied O-rings into the groove in the bottom of the regulator mount and 

install the fuel pressure regulator/ mount assembly onto the rear of the passenger side rail. Fasten it to 

the rail using the supplied 

6-32 x 3/4”

 screws.

STEP 17

 Place the remaining O-ring over the fuel rail end cap and push the cap into the front end of 

the driver side rail. Secure it using the remaining 

10-32 x 5/8”

 button head screw. 

STEP 18

 Thread the 1 of the supplied 90° fittings into the rear of each fuel rail until snug. Then con

-

tinue tightening until the outlets will face each other once the rails are installed.

STEP 19

 Push one end of the supplied crossover hose fully onto one of the 90° fittings.

STEP 20 

Thread the long pre-assembled hose into the regulator mount until its snug. Then tighten it 

until it is following the rail forward to meet up with the stock fuel return line.

STEP 21 

Thread the short pre-assembled hose into the front end of the passenger side rail until its 

snug. Then tighten it until it is pointing towards the passenger side of the car to meet up with the stock 

fuel feed line.

STEP 22 

Insert the injectors into the rails 

(we recommend lightly lubricating the outsides of each 

O-ring to ensure proper seating).

STEP 23 

(Follow for both rail/injectors assemblies) 

carefully guide each injector into its injector port 

on the lower manifold. Tighten the supplied fasteners through the fuel rail mounting tabs and into the 

lower manifold.

STEP 24 

Determine the proper length for the crossover hose and cut it to fit. Push the cut end fully 

onto the other 90° fitting 

(if necessary, rotate the fittings to line up.)

STEP 25 

Connect the spring lock fittings on the fuel rails and regulator to the stock fuel feed and return 

lines.

 

 

 

 

    

   

 

 

 

 

 

  TESTING THE FUEL RAILS FOR LEAKS

      TO AVOID SHOCK/ FIRE/WORSE, WE STRONGLY RECCOMEND FOLLOWING THE 

      INSTRUCTIONS FOR THE NEXT PROCEDURE CLOSELY!

STEP 26 

Disconnect the electrical connector from the ignition coil

 

(this may require removing the 

plastic cover located between the battery and the strut tower).

STEP 27  

If the car has automatic door locks or an alarm, be sure to leave the driver door open while 

following this step. Otherwise the doors might lock with the key in the ignition). With the negative bat

-

tery cable disconnected turn the ignition key to the on position. While watching the fuel rails and con

-

nections, touch the negative battery cable to the negative terminal of the battery for 3 seconds then 

stop.

 

(This will turn the fuel pump on momentarily and pressurize the fuel rails. If you have any 

leaks in the connections or fittings this will allow you to find and repair them before you put the 

upper intake manifold back on). 

Once you have verified that there are no fuel leaks in your system 

turn the key back to off.            

                          

STEP 28 

Re-install the upper intake manifold and re-establish all electrical, coolant, vacuum, and cable 

connections at the throttle body, EGR valve, IAC valve, ignition coil, and the upper intake manifold.

STEP 29 If you followed STEP 3; 

re-install the lower cup, rotor, cap, and distributor wires.

STEP 30 

Connect the intake hose between the mass air meter and throttle body.

STEP 31 

Re-connect the negative battery terminal.
