Step #16 Modify Fuel Pressure Regulator:
• Remove the trunk mat to access the fuel tank access panel (A).
• Remove the three screws holding the panel and disconnect the 5 pin harness connector (B). Wrap a rag around the fuel line. Pinch the release tabs and disconnect the fuel line.
• Use the factory Honda tool to remove the top of the pump/sender assembly (we have found you can also use a larger flat bladed screw driver as a punch to remove it also).
• Using rags to catch the fuel, slowly pull the pump assembly out of the tank be very careful not to damage the sending unit float.
• Once the assemble is out disconnect the sending unit harness from the top (I) releases the clips and pull the pump out of the reservoir tank (D).
• Once out of the reservoir tank the fuel pressure regulator (F) can be accessed.
Release the side clips on the plastic regulator housing and pull it off the bottom of the filter. Remove the R clip (A) remove the regulator make sure to keep all of the seals and spacers in order, they will be reused.
• Using the supplied (2 piece) tool very carefully compress the regulator about .030” of an inch. This can be done in a bench vice. This will raise the fuel pressure about
10 psi. See note below.
• Reinstall the regulator with the hole (D) pointing down.
• Reassemble everything in the reverse order as removal. We have found that when you are just about to install top of the pump assemble (B) into the tank, slip the seal (J) in to the top of the tank first. Make sure to line up the top of the pump assemble (B
& M) with the tank
(L).

Note: Insert FPR into large piece of tool with o-ring end first. Then place cap of tool in center of FPR. Compress two pieces of FPR tool until this gap is taken up.
Step #17A Installing ACM (Advanced Control Module):
2004-2005 only. See next page for 2006 install
•
•
Locate the ECM under the center console.
Disconnect connector “E” and plug the ACM jumper harness in
•
• between the ECM and wiring harness.
Locate the Green/Red wire at pin #D5 and cut the wire about
2” from the connector. Using the solder splice connectors, connect the Green wire from the ACM to the Green/Red going to the ECM and connect the White/Green wire from the ACM to the Green/Red wire going to the engine.
Place the ACM in the area on the floor above the ECU Harness and reinstall the carpet.
How to use Solder Splice Connectors:
Strip about 1/4” of insulation off each wire and insert the wire into the end of the solder splice connector, overlapping the bare wire in the middle by the solder ring. Slowly heat the outer edges of the heat shrink until the color ring melts. Once they are melted, heat the center until the solder melts connecting the wires.
