Parts

• Fuel pump module assembly × 1 — 17045-TVA-A00 or 17045-TVA-A10 depending on model year

Preparation

1. Ensure fuel tank is less than 1/4 full. If necessary, siphon or drive vehicle to reduce fuel level
2. Park vehicle on level ground in well-ventilated area away from ignition sources
3. Position ABC-rated fire extinguisher within immediate reach
4. Allow engine to cool completely if vehicle was recently operated (minimum 30 minutes)
5. Disconnect negative battery terminal and wait 3 minutes for system capacitors to discharge
6. Remove rear seat cushion by pulling up firmly on front edge until clips release, then lift out
7. Verify access to fuel pump module cover beneath rear seat on driver side of vehicle
8. Gather all tools, new fuel pump module, and replacement O-rings before beginning

Procedure

1. 1

   Depressurize fuel system
   With battery still disconnected, locate the fuel pump relay in the under-hood fuse box (relay position R19 - 'FUEL PUMP' marked on diagram). Remove the fuel pump relay. Reconnect battery and start the engine. Allow engine to run until it stalls from fuel starvation (typically 30-90 seconds). Attempt to restart engine 2-3 times to ensure all fuel pressure is relieved. Turn ignition OFF. Disconnect negative battery terminal again and remove key from vehicle.
2. 2

   Remove access cover
   Locate the rectangular plastic access cover beneath the rear seat on driver side. Clean any dirt or debris from around the cover to prevent contamination from entering fuel tank. Remove the four Phillips screws securing the access cover. Remove cover and set aside with screws. You should now see the top of the fuel pump module with electrical connector and fuel lines attached.

3. 3

   Disconnect electrical connector
   Press down on the locking tab of the fuel pump module electrical connector while pulling upward to disconnect. Inspect connector and pins for corrosion or damage. Clean with electrical contact cleaner if needed. Position connector away from work area to prevent fuel contamination.
4. 4

   Disconnect fuel supply line
   Place shop towels around fuel line connection to catch residual fuel (expect 50-100ml). Identify the fuel supply line (larger diameter, typically 10mm). Press the quick-disconnect tool into the connector while pulling the fuel line away from module. If line is difficult to remove, rotate slightly while pulling. Cap or plug the fuel line immediately to prevent contamination. Replace fuel line O-ring with new part - do not reuse old O-ring.
5. 5

   Disconnect fuel return/vapor lines
   Using appropriate quick-disconnect tools, disconnect the remaining fuel return and evaporative emission lines from the fuel pump module. Note the position and routing of each line for reassembly - taking a photo is recommended. Place additional shop towels to catch residual fuel. Cap all open fuel lines to prevent contamination and evaporation.
6. 6

   Remove fuel pump lock ring
   Install the fuel pump lock ring tool (Honda 07LAA-SOXA100 or equivalent) onto the lock ring tabs. The lock ring rotates counterclockwise to loosen. Apply steady force to break the initial seal - it may require significant effort. Rotate lock ring counterclockwise until completely disengaged. Remove lock ring and set aside. Do not lose the lock ring as it is not typically included with replacement module.

7. 7

   Remove fuel pump module
   Carefully lift the fuel pump module assembly straight up and out of the tank opening. Tilt the module slightly to navigate the fuel level sender arm through the opening. Be aware that residual fuel will drain from the module - have shop towels ready. Keep module upright and contained over drip pan. Once clear, place module in drip pan and allow to drain completely. Do not allow module to contact vehicle interior surfaces.
8. 8

   Inspect tank opening and prepare new module
   Inspect inside top of fuel tank for debris, contamination, or damage using flashlight. Remove any visible debris with clean lint-free cloth - do not introduce any foreign material. Check tank opening seal surface for scratches or damage that could prevent proper seal. Remove the old O-ring seal from the tank opening groove and clean groove thoroughly. Unpack new fuel pump module and verify it matches old unit configuration. Install new O-ring seal into the groove on top of fuel tank opening - ensure it seats fully without twisting.
9. 9

   Install new fuel pump module
   Orient new fuel pump module with alignment marks or tabs matching tank opening. Carefully lower module into tank while guiding fuel level sender arm through opening. Ensure module seats fully against O-ring seal - there should be no gap. Verify module is not rotated or misaligned. The module must sit flat against the tank seal surface before installing lock ring.
10. 10

    Install and torque lock ring
    Place lock ring over fuel pump module and engage the tabs with module grooves. Using the lock ring tool, rotate clockwise while applying downward pressure to engage threads. Continue rotating clockwise until resistance is felt. Torque to specification using calibrated torque wrench - this is critical for proper fuel seal. After torquing, verify O-ring has not shifted and module remains fully seated.

    Connect fuel lines
    Install new O-rings on all fuel line fittings - lubricate lightly with clean gasoline. Connect fuel supply line (larger diameter) first by pushing firmly onto module fitting until you hear/feel a distinct click. Tug on line to verify it is locked. Connect return and vapor lines in same manner, referencing photos from disassembly. Verify all lines are fully seated and locked - improper connection will cause fuel leaks and/or check engine light.
12. 12

    Connect electrical and test
    Reconnect electrical connector to fuel pump module by pressing firmly until locking tab clicks into place. Tug gently to verify connection. Wipe away any spilled fuel from access area using shop towels. Reconnect negative battery terminal. Turn ignition to ON position (do not start) for 5 seconds, then OFF. Repeat this cycle 3-4 times to prime fuel system and pressurize lines. During priming, carefully inspect all fuel line connections for leaks using flashlight - any fuel seepage requires immediate correction.
13. 13

    Reinstall access cover
    Verify no tools or parts remain in access area. Ensure all connections are tight and no fuel is present on surfaces. Reinstall access cover and secure with four screws torqued to specification in cross-pattern. Do not overtighten plastic screws.

Reassembly

1. Reinstall rear seat cushion by aligning rear hooks with floor brackets, then pressing down firmly on front edge until clips engage
2. Verify seat is properly secured before use
3. Reinstall fuel pump relay in under-hood fuse box (position R19)

Verification

• Turn ignition to ON position (engine not running) and listen for fuel pump operation for approximately 2 seconds - this confirms electrical connection
• Start engine and verify it runs smoothly without hesitation or surging
• Check for fuel odor inside cabin and in trunk/access area - any fuel smell indicates a leak that must be corrected immediately
• Remove access cover and inspect all fuel line connections for leaks while engine is running - use flashlight to look for wetness or drips
• Allow engine to reach operating temperature and verify no fuel leaks develop under pressure
• Check for diagnostic trouble codes using scan tool - codes P0087 (fuel pressure too low) or P0230 (fuel pump circuit) indicate installation problems
• Road test vehicle to verify normal acceleration and no fuel delivery issues under load
• Re-inspect all connections after 50-100 miles of driving as final safety check
