Things You'll Need:
- Socket wrench
- Flat-head and Phillips screwdriver
- Locknut tool
- Fuel filter assembly
- O-ring
-
Step 1
Relieve the fuel system's pressure. On coupes, sedans and hatchbacks, remove the PGM-FI relay No. 2. On CR-Vs, remove the engine cover and use a wrench to loosen the pulsation damper by a full turn.
-
Step 2
Disconnect the negative battery cable. On some models, you will need to have the anti-theft code for the radio available so you can program it after reconnecting the battery.
-
Step 3
Remove the rear seat cushion on a coupe, sedan or hatchback by removing the cushion's retaining bolt; it's within the crack between the cushion and backrest and requires a socket wrench with an extra-long socket. On a CR-V, fold the back seats forward and pull back the carpet to find the fuel pump's access cover.
-
Step 4
Open the fuel pump's access cover by removing its four screws--one at each corner-- to access the fuel pump/fuel gauge sending unit.
-
Step 5
Disconnect the electrical connector for the unit by depressing its release tab. Disconnect the fuel supply line by pressing the tabs on the quick-connect fitting. Remove the unit's locknut; this will require a special tool found at most auto parts stores.
-
Step 6
Remove the unit from the fuel tank. Tilt the unit while removing it to protect the float and float arm from being damaged.
-
Step 1
Place the fuel pump/fuel gauge sending unit on a clean workbench.
-
Step 2
Disconnect the fuel pressure regulator from the unit. Disconnect its return hose fitting by spreading the locking tabs apart. Detach the inlet fitting by pressing the locking tab with a screwdriver, remove the clip from the regulator and pull the regulator out of the inlet hose fitting.
-
Step 3
Separate the fuel filter assembly from the fuel pump housing by turning the unit upside down, removing the stops (a screwdriver will disengage their locking tabs) and releasing the hooks to separate the spring-loaded legs. Disconnect all hoses and electrical connectors on the filter assembly.
-
Step 4
Connect the new filter assembly onto the fuel pump unit, inserting the legs in place until the hooks and locking tabs engage and reconnecting the electrical connectors and hoses.
-
Step 5
Re-connect the pressure regulator to the unit. Make sure the regulator's clip still has the smaller clip inside it.
-
Step 1
Install the fuel pump unit back into the fuel tank. Make sure the the seal in the tank's hole is in place and align the index mark at the top of the unit in between the two marks on the edge of the hole.
-
Step 2
Replace the O-ring inside the quick-connect fitting of the fuel supply line before reconnecting the line to the unit.
-
Step 3
Tighten the unit's locknut securely and reconnect the electrical connector.
-
Step 4
Re-install the relay or tighten the pulsation dampener so you can re-pressurize the fuel system.
-
Step 5
Reconnect the battery cable and start the vehicle. Check for leaks around the unit's connection to the fuel line. Do this before installing the fuel pump access cover and the seats.
