STEP #33 Fuel Rail Installation Prep: • Make sure the injector adaptor bushings are pushed

all the way into the manifold. These adaptors make the Comptech manifold work with the Honda factory fuel injectors.

• Install the supplied bushings onto each stud along with the original fuel rail spacers.

STEP #32 Install Spark Plugs: • Remove the Ignition Coil cover

(A). • Remove the Coils (C). • Remove the stock spark plugs. • Install the supplied Denso IK24

plugs. • Reinstall the coils and ignition coil

cover. • Reinstall the cowlings in the re-

verse order of removal.

STEP #34 Install Fuel Rail: • Use a small amount of oil on the fuel injector seal and

reinstall the fuel rail with all of the injectors still in the rail. Use the supplied spacer nuts to secure the rail to the manifold.

• Reconnect the fuel supply hose and connector cover. A small amount of oil on the end will help.

STEP #31 Remove cowl-ings: • Remove plastic cowling

at the base of the windshield.

• Remove steel panel below plastic cowling.

STEP #36 Install Throttle Body: • Install the studs removed in step #10 in to the new

inlet manifold. • Using the supplied new throttle body gasket and origi-

nal hardware, mount the throttle body to the blower inlet manifold.

STEP #37 Throttle Body Connections: • Reconnect the throttle body wiring connector. • Reinstall the two water lines to the bottom of the

throttle body that were removed in step #8.

STEP #38 Install Vacuum Lines: • Using the supplied 5/16 x 12” hose connect the brake

booster hard line to the top fitting on the new inlet manifold.

• Reinstall the factory EVAP hose. • Route the PCV hose installed in step #25 along the

radiator support. Connect it to the lower fitting on the new lower inlet manifold.

STEP #35 Reinstall Manifold Wiring Harness: • Reinstall the factory wiring harness cover onto the rail

and reconnect each fuel injector. • Open the right side plastic harness guide by releasing

the five clips. Free the ground and MAP sensor wires from the harness by removing the black tape wrap-ping and short length of corrugated plastic sheathing. Route the ground wire to the boss just below the cam cover on the right end of the cylinder head. Route the MAP sensor wire under the inlet cast-ing to the new MAP sensor loca-tion.

STEP #40 Refill Cooling System: • Refill the cool-

ing system us-ing a mixture of 50% antifreeze and 50% water.

• Fill the radiator to the base of the filler neck.

• Loosely install the radiator cap and proceed to step#41.

STEP #41 Raise Fuel line pressure: • Remove the rear lower seat cushion (Note: M6 bolt attaching lower cushion is located slightly to left of center between

upper and lower cushions.). • Remove trunk floor panel by unsnapping front edge of panel from cross member. • Remove the access panel (A) from the floor (attached with four M8 bolts) and then remove the fuel sender access

panel (B) (attached with four Phillips Head screws). Disconnect the electrical connector (C), and using a rag to catch the excess fuel, remove the fuel and vent lines (D) by releasing quick disconnect fittings from the top of the pump/sender unit.

• Use the factory Honda tool to unscrew the plastic fuel pump retaining ring (E) (We have also found you can also use a larger flat bladed screw driver as a punch to remove it.).

• Using rags to catch the fuel, slowly pull the pump assembly out of the tank, tipping it forward as it comes up to pre-vent damaging the sending unit float. With the fuel pump/sender unit on a counter, remove the plastic lower cover to gain access to the fuel pressure regulator. The fuel pump and sender wire plugs must be disconnected from the un-derside of the pump/sender unit and released from a clip to do this.

• Working from the bottom of the pump, remove the fuel pressure regulator retaining clip (F), ground ring (G) and re-move regulator. Remove the o-rings (I) from the regulator, and using the supplied setting tool, insert the regulator into the tool and compress in a vice until the regulator flange is bottomed out on the tool. (See photos)

• Re-install the o-rings on the regulator and push back into the pump/sender assembly (a little oil on the o-rings will help). Reverse the disassembly process to finish assembly of pump.

• Install the pump/sender unit into tank and attach electrical and fuel connections. Make sure to get the top of the unit clocked correctly in the tank (see drawing). Reconnect the electrical connector and fuel line.

• Install covers, trunk flooring, and seat cushion.
