🔧 Accord - Fuel Pump Replacement

On your Accord, the fuel pump sits inside the fuel tank as part of an in-tank pump module. The job is done from inside the car under the rear seat, so you don’t need to drop the tank, but you must relieve fuel pressure and keep everything very clean to avoid leaks.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours

⚠️ Safety & Precautions

• ⚠️ Work outside or in a well-ventilated area—fuel vapors are flammable.
• ⚠️ No smoking, no sparks, no shop lights with hot bulbs near the open tank.
• ⚠️ Relieve fuel pressure before disconnecting any fuel line to prevent fuel spray.
• ⚠️ Disconnect the negative battery cable before opening the pump module.
• ⚠️ Keep dirt out of the tank—clean the area before you open it.

📋 Before You Begin

• Park on level ground, set the parking brake, and open the fuel door.
• Remove the fuel filler cap to release tank vapor pressure.
• Relieve fuel pressure: pull the PGM-FI (fuel injection) fuse from the under-hood fuse/relay box, start the engine, and let it stall. Crank for 2–3 seconds again. Then turn the key OFF.
• Disconnect the battery: use a 10mm socket to remove the negative (-) battery cable and isolate it.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear seat bottom cushion

• Use a flat trim tool to pop the front seat-cushion clips (pull up sharply at the front edge).
• If equipped with seat bolts, remove them with a 10mm socket and ratchet.
• Lift the cushion out of the car.

Step 2: Remove the fuel pump access cover

• Locate the service cover on the floor under the rear seat (center area).
• Remove the cover fasteners with a 10mm socket (or Phillips #2 screwdriver, depending on fastener style).
• Lift the cover and set it aside.

Step 3: Clean the area and disconnect the pump wiring

• Wipe/vacuum dirt around the pump module opening using shop towels. Cleanliness prevents leaks and clogging.
• Unplug the electrical connector(s) from the pump module by releasing the tab with a flat trim tool.

Step 4: Disconnect the fuel line(s)

• Place a small catch pan and shop towels under the connection.
• Release the quick-connect fitting using fuel line disconnect pliers (specialty) (or depress the connector tabs if your fitting uses tabs), then pull the line straight off.
• Cap or wrap the line with shop towels to keep dirt out.

Step 5: Remove the fuel pump locking ring

• The locking ring is the large ring that holds the module to the tank.
• Use a brass punch (specialty) and small hammer to tap the ring counterclockwise until it releases. (Brass is used because it’s less likely to spark.)
• Remove the ring and set it aside.

Step 6: Remove the fuel pump module

• Carefully lift the module straight up. Tilt it as needed to clear the float arm.
• Let fuel drain into the tank, then move the module to the catch pan.
• Remove the old tank seal (O-ring/gasket) from the tank opening and discard it.

Step 7: Install the new seal and pump module

• Install the new tank seal into the groove on the tank opening (do not reuse the old one).
• Lower the new module in carefully, guiding the float arm so it doesn’t bend.
• Align the module’s index marks with the tank marks.

Step 8: Reinstall and tighten the locking ring

• Install the locking ring by hand first to avoid cross-threading.
• Tap it clockwise with the brass punch (specialty) and small hammer until fully seated and aligned.
• If using the factory-style lock ring tightening method with a torque adapter tool: Torque to 93 N·m (69 ft-lbs).

Step 9: Reconnect fuel line(s) and wiring

• Reconnect the quick-connect fuel line until it clicks; tug lightly to confirm it’s locked.
• Plug in the electrical connector(s) until the tab clicks.

Step 10: Reinstall the access cover and rear seat

• Reinstall the service cover fasteners with a 10mm socket or Phillips #2 screwdriver.
• Torque to 9 N·m (80 in-lbs) if using a torque wrench.
• Reinstall the rear seat cushion and any bolts removed with a 10mm socket.
• Torque to 12 N·m (9 ft-lbs) for seat bolts (if equipped).

✅ After Repair

• Reinstall the PGM-FI fuse.
• Reconnect the negative battery cable with a 10mm socket and ratchet. Torque to 5 N·m (44 in-lbs).
• Prime the system: turn key to ON for 2 seconds, OFF for 2 seconds. Repeat 3 times.
• Start the engine and inspect for leaks at the pump seal and fuel line connection for 2–3 minutes.
• If you smell fuel or see seepage: shut it off immediately and recheck the seal/ring alignment.
