🔧 Accord - In-Tank Fuel Pump Module Replacement

The low-pressure fuel pump is inside the fuel tank and is reached from beneath the rear seat. Because certain Accord fuel pumps are covered by a safety recall for a defective impeller, check recall eligibility before buying parts; an authorized Honda dealer may replace it at no charge.

Difficulty Level: Advanced | Estimated Time: 2-3 hours

Assumption: This procedure covers the complete in-tank fuel-pump module, not wiring diagnosis or recall-specific pump-motor rebuilding.

📋 Before You Begin

• 🚗 Park your Accord outdoors on level pavement, select Park, apply the parking brake, and lower all windows.
• ⛽ Run the fuel level down to one-quarter tank or less. Fuel expands with heat, so allow the vehicle to cool before opening the tank.
• 📱 No infotainment service mode, battery registration, EPB command, or high-voltage isolation procedure is required.
• 🔎 Check the NHTSA recall-lookup website or contact an authorized Honda dealer before purchasing parts. Do not provide a VIN here; enter it only through an official recall-lookup service.
• 🧹 Remove loose items from the rear seating area and place fuel-safe absorbent pads around the work area.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve Residual Fuel Pressure

• Switch the climate control off, place the transmission in Park, and switch the vehicle completely off.
• Open the fuel-filler door and slowly loosen the fuel cap by hand to release tank vapor pressure. Reinstall the cap after pressure equalizes.
• Wait at least three minutes before disconnecting the battery.
• No tool is required for this step.

Step 2: Disconnect the 12-Volt Battery

• Keep the key fob at least 10 feet away from your Accord.
• Use a 10mm socket and 3/8-inch drive ratchet to loosen the negative battery-terminal nut.
• Lift the negative clamp from the terminal and isolate it so it cannot make accidental contact.
• Do not disconnect any orange high-voltage component.

Step 3: Remove the Rear Seat Cushion

• Reach beneath the front edge of the rear seat cushion and locate the cushion-release points.
• Release the cushion retainers by hand. Use a nylon trim-clip removal tool only if gentle assistance is necessary.
• Lift the front of the cushion, disengage its rear hooks, and remove it through a rear door.
• Do not force the cushion around seat-belt buckles or nearby wiring.
• Photograph every clip before removal.

Step 4: Expose and Clean the Pump Access Area

• Locate the fuel-pump access cover beneath the removed seat cushion.
• Use a plastic scraper 25mm wide to separate the access cover from its butyl sealer without bending the cover.
• Use a compressed-air blow gun regulated below 30 psi to blow dirt away from the pump-module flange before disconnecting anything.
• Position fuel-safe absorbent pads and a fuel-safe drain pan rated 2 gallons around the module.
• Do not allow dirt to enter the fuel tank.

Step 5: Disconnect the Electrical Connector and Fuel Line

• Press the locking tab and disconnect the fuel-pump electrical connector by hand. Pull on the connector body, not its wires.
• Wrap the fuel connection with a fuel-safe absorbent pad.
• Release the fuel-line connector using the correctly sized tool from the fuel-line quick-connector release tool set.
• A quick connector is the locking fitting that secures the plastic fuel line without a threaded nut.
• Pull the fuel line straight from the module nipple and collect the small amount of released fuel in the fuel-safe drain pan rated 2 gallons.
• Inspect the connector for broken tabs, deformation, or contamination.

Step 6: Mark and Remove the Lock Ring

• Use the flat-blade screwdriver with 6mm tip only to make a light orientation reference on the removable ring area; do not puncture or pry against the tank.
• Fit the fuel tank lock-ring wrench sized for Honda module squarely onto the lock ring.
• Use the 3/8-inch drive ratchet with the lock-ring wrench to turn the ring counterclockwise.
• Do not use an impact wrench, hammer, or steel punch.
• Remove the lock ring and place it on a clean, dry surface.

Step 7: Remove the Fuel-Pump Module

• Lift the module slowly by hand while watching the fuel-level float arm.
• Tilt the module only enough to clear the tank opening without bending the float arm.
• Drain retained gasoline from the module into the fuel-safe drain pan rated 2 gallons.
• Remove and discard the old tank seal. Never reuse a compressed seal.
• Cover the opening temporarily with a clean, fuel-safe absorbent pad. Do not push the pad into the tank.

Step 8: Compare and Install the New Module

• Compare the new and old modules on a clean surface. Confirm that the connector, fuel outlet, float arm, filter, and locating features match.
• Install a new fuel-pump module tank seal into the tank groove by hand. Keep it dry unless the replacement-part instructions specify otherwise.
• Lower the new module into the tank by hand while carefully guiding the float arm through the opening.
• Align the module’s locating mark with the corresponding tank mark. The module must sit flat without compressing or displacing the seal.
• Never force the float arm downward.

Step 9: Install and Tighten the Lock Ring

• Start the lock ring by hand and confirm that it engages evenly.
• Install the fuel tank lock-ring wrench sized for Honda module and turn the ring clockwise with the 3/8-inch drive ratchet.
• Align the lock ring to Honda’s fully seated index position. Honda uses a lock-ring seating position for this joint rather than a universal fastener torque.
• If the replacement module includes a different ring or installation specification, follow the instructions supplied with that exact matched component.
• Stop and reseat the seal if the ring binds or the module flange rises unevenly.

Step 10: Reconnect the Fuel Line and Wiring

• Install the new fuel-line connector retainer in its specified position.
• Push the fuel-line connector straight onto the module nipple by hand until it clicks.
• Pull gently on the connector by hand to confirm it is locked.
• Connect the electrical connector until its locking tab clicks.
• Use a fuel-safe absorbent pad to dry the surrounding area completely.

Step 11: Reconnect the Battery and Prime the System

• Use a 10mm socket and 3/8-inch drive torque wrench rated 5-80 ft-lbs to reconnect the negative battery terminal.
• Torque the 12-volt negative terminal nut to 5.4 Nm (48 in-lbs).
• With the access cover and seat still removed, enter the vehicle with dry gloves and press the brake pedal while pressing the POWER button.
• Confirm that the green READY indicator illuminates. The engine may or may not start immediately; this is normal for the hybrid system.
• Switch the vehicle off, wait 30 seconds, and repeat the READY cycle twice to prime the fuel system.

Step 12: Check for Leaks

• With your Accord in READY mode, inspect the module flange and fuel-line connector visually.
• Use a clean fuel-safe absorbent pad to touch the outside of the joint carefully. The pad must remain completely dry.
• Switch the vehicle off immediately if you see fuel, smell strong gasoline vapor, or find wetness.
• Do not reinstall the access cover until the system remains completely dry through several READY cycles.

Step 13: Reinstall the Access Cover and Rear Seat

• Switch your Accord off and move the key fob away.
• Apply new fuel-pump access-cover butyl sealer around the cover’s original sealing path.
• Press the access cover into place by hand, making sure the sealer forms an uninterrupted seal.
• Position the rear seat cushion, engage its rear hooks, and route the seat-belt buckles through their openings.
• Press directly above each front retainer until it locks. Pull upward gently to confirm the cushion is secure.
• No fastener torque applies to a cushion retained only by hooks and snap retainers.

✅ After Repair

• ✅ Start your Accord in READY mode and confirm that no warning message appears.
• 👃 Check inside and outside the vehicle for gasoline odor before driving.
• 🔍 Reinspect beneath the rear seat for leaks after a short drive and again after filling the tank.
• ⛽ Do not top off the tank during the first refueling. Stop when the pump nozzle clicks off automatically.
• 🛑 If the vehicle does not enter READY mode, cranks without starting, or develops a fuel leak, switch it off and recheck the connector and fuel-line lock.
• 📟 A warning light that remains on requires diagnosis with a Honda-capable scan tool; do not replace additional components without testing.
