🔧 Accord - Fuel Pump Replacement

On your Accord, the fuel pump sits inside the fuel tank as a “fuel pump module” (pump + level sensor + housing). The job is mostly interior work: remove the rear seat, open the access cover, swap the module, then verify there are no leaks.

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

Assumption: This is the in-tank fuel pump module accessed under the rear seat.

⚠️ Safety & Precautions

• ⚠️ Work outside or in a well-ventilated area; gasoline fumes ignite easily.
• ⚠️ No smoking, no hot lights, no power tools that can spark near the open tank.
• ⚠️ Wear safety glasses and fuel-resistant gloves; fuel can splash under pressure.
• ⚠️ Disconnect the negative battery cable to prevent sparks.
• ⚠️ Keep a class B fire extinguisher nearby.
• ⚠️ Wipe spills immediately and dispose of rags safely.

📋 Before You Begin

• Park on level ground, set the parking brake, and open the driver window (so you can get back in if the car auto-locks).
• Relieve fuel pressure: remove the fuel pump fuse, start the engine, and let it run until it stalls. Crank for 2–3 seconds to release leftover pressure.
• Turn ignition OFF and remove the key.
• Disconnect the negative battery cable using a 10mm socket.
• Clean the area around the fuel pump access cover so dirt can’t fall into the tank.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear seat bottom cushion

• Use a trim removal tool to pop the front seat-cushion clips (pull up firmly at the front edge).
• Lift the cushion out and set it aside.

Step 2: Open the fuel pump access cover

• Locate the metal access cover in the floor under the seat area.
• Remove the cover fasteners with a Phillips screwdriver #2 or 10mm socket (fastener type varies).
• Peel back any butyl sealer carefully and remove the cover.
• Tip: Keep dirt out of the open area.

Step 3: Disconnect the electrical connector

• Press the lock tab and unplug the module connector by hand.

Step 4: Disconnect the fuel line(s)

• Place shop towels under the line connection and a catch pan nearby.
• Release the quick-connect fitting using a fuel line quick-disconnect tool set (this tool slides into the connector to release the internal spring).
• Pull the line straight off. Expect a small amount of fuel to drip.
• If there are retainer clips, remove them with needle-nose pliers.

Step 5: Mark the module orientation

• Use a marker pen to draw an alignment mark from the tank to the module top hat.
• This helps the new module seat the same way and prevents hose/float interference.

Step 6: Remove the lock ring

• The module is held by a large plastic lock ring.
• Use a brass punch set (non-sparking) (specialty) and small hammer to tap the ring counterclockwise until it unlocks.
• Lift the ring off and set it aside.

Step 7: Remove the fuel pump module

• Slowly lift the module straight up. Tilt it as needed to clear the float arm (the thin arm that measures fuel level).
• Let fuel drain back into the tank for a few seconds, then move the module to the catch pan.
• Remove the old tank seal (O-ring/gasket) from the tank opening by hand.

Step 8: Install the new seal and module

• Install the new tank seal in the groove on the tank opening (or as supplied by the kit).
• Lower the new module in, guiding the float arm so it doesn’t bend.
• Line up your marker marks so the module sits in the correct orientation.
• Tip: Do not pinch the seal.

Step 9: Reinstall and tighten the lock ring

• Install the lock ring and turn it clockwise by hand as far as possible.
• Use the brass punch set (non-sparking) (specialty) and small hammer to tap the ring clockwise until it fully seats/locks.
• If your replacement uses bolts instead of a lock ring, tighten evenly in a crisscross pattern with a 10mm socket and torque wrench.
• Torque to: Refer to the spec supplied with the module/lock ring; do not overtighten plastic.

Step 10: Reconnect fuel line(s) and electrical

• Push the fuel line on until you feel/hear a solid click.
• Gently tug to confirm it’s locked.
• Reinstall any clips using needle-nose pliers.
• Plug in the electrical connector until it clicks.

Step 11: Reinstall the access cover and rear seat

• Reinstall the access cover and fasteners using a Phillips screwdriver #2 or 10mm socket.
• Reinstall the rear seat cushion: align the rear tabs, then push down at the front until the clips snap in.

✅ After Repair

• Reconnect the negative battery cable using a 10mm socket. Torque to 5 Nm (44 in-lbs) (snug, do not strip).
• Reinstall the fuel pump fuse.
• Prime the system: key ON for 5 seconds, key OFF for 5 seconds—repeat 3 times (listen for the pump hum).
• Start the engine and let it idle. Check carefully for fuel smell or wetness at the line connection and around the lock ring area.
• Test drive 5–10 minutes, then recheck for leaks.
• If the fuel gauge reads wrong, recheck module orientation and connector seating.
