🔧 Camry - Fuel Pump Replacement
The fuel pump on your Camry is inside the fuel tank as part of the fuel pump/sender module. On this model, you typically access it through a service cover under the rear seat, so you usually do not have to drop the fuel tank.

⚠️ Safety & Precautions
- 🧯 Work outside or in a well-ventilated area; fuel vapors ignite easily.

- Fuel pump module tank seal/O-ring - Qty: 1
- Fuel pump strainer (sock filter) - Qty: 1
- Fuel line clip(s) - Qty: 1-2
📋 Before You Begin
- Park on level ground, set the parking brake, and keep doors open for ventilation.
- Run the fuel level down to about 1/4 tank or less; it reduces spill risk.
- Open the trunk and remove anything that could block rear seat access.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Relieve fuel pressure
- Open the hood.
- Use a 10mm socket to loosen the negative battery terminal and remove it. Torque to 5 Nm (44 in-lbs) on reassembly.
- Locate the under-hood fuse/relay box and remove the fuel pump fuse or circuit opening relay (labeling varies).
- Reconnect the negative battery cable temporarily using the 10mm socket.
- Start the engine and let it run until it stalls. Crank for 2–3 seconds more, then turn the key OFF.
- Disconnect the negative battery cable again with the 10mm socket.
- Tip: This step greatly reduces fuel spray.
Step 2: Remove the rear seat cushion
- From the back seat footwell area, locate the seat cushion retainers/bolts at the front edge.
- If your cushion uses bolts, remove them using a 12mm socket. Torque to 37 Nm (27 ft-lbs) on reassembly.
- If your cushion uses clips, use a trim clip removal tool to pop the front edge up.
- Lift the seat cushion out and set it aside.
Step 3: Open the fuel pump service cover
- Find the oval/round metal access cover on the floor under the seat.
- Remove the cover screws/bolts using a Phillips screwdriver #2 or 10mm socket (varies).
- Lift the cover. Use shop towels to wipe away dust so it can’t fall into the tank.
Step 4: Disconnect electrical connector and fuel line
- Unplug the pump/module electrical connector by releasing the lock tab with a small flat-blade screwdriver.
- Place a catch pan and shop towels under the fuel line connection.
- Release the quick-connect fuel line:
- Use a small flat-blade screwdriver to gently lift the connector lock (if equipped).
- Squeeze the connector tabs by hand and pull the line straight off.
- Use needle-nose pliers only if needed, and don’t crush the connector.
Step 5: Remove the pump module lock ring
- Mark the module and tank alignment with a marker (so you reinstall in the same orientation).
- Use a non-sparking brass punch (specialty) and small hammer to tap the lock ring counterclockwise until it releases.
- Remove the lock ring and set it aside.
- Tip: Tap gently; avoid sparks and cracked plastic.
Step 6: Remove the fuel pump module
- Lift the module straight up slowly.
- Angle it as needed to clear the float arm (fuel level sensor) without bending it.
- Let fuel drain from the module into the tank for a few seconds, then move it to the catch pan.
- Remove and discard the old tank seal/O-ring.
Step 7: Swap pump parts (if you’re not replacing the whole module)
- If you bought a complete module, skip to Step 8.
- On a bench, use a Phillips screwdriver #2 and small flat-blade screwdriver to release the internal clips and remove the pump.
- Install the new fuel pump strainer (sock filter) and make sure it fully seats.
- Reassemble the module exactly as it came apart.
Step 8: Install new seal and reinstall the module
- Install the new tank seal/O-ring in the tank opening (not on the module unless your seal design requires it).
- Lower the module into the tank, keeping the float arm safe.
- Align your marks and seat the module fully.
- Reinstall the lock ring and tap it clockwise using the brass punch and hammer until it is fully locked and aligned.
Step 9: Reconnect fuel line and electrical connector
- Push the fuel line quick-connect on until it clicks.
- Gently tug the line to confirm it’s locked.
- Reconnect the electrical connector until it clicks.
Step 10: Reinstall service cover and rear seat
- Reinstall the access cover using a Phillips screwdriver #2 or 10mm socket.
- Reinstall the rear seat cushion:
- Position it and press down to engage clips, or reinstall bolts using a 12mm socket.
- Torque to 37 Nm (27 ft-lbs) if bolts are equipped.
- Reconnect the negative battery terminal using a 10mm socket. Torque to 5 Nm (44 in-lbs)
✅ After Repair
- Turn the key to ON (not START) for 3 seconds, then OFF. Repeat 3 times to prime the system.
- Start the engine and let it idle.
- Check carefully for fuel leaks at the quick-connect and around the lock ring area.
- If you smell fuel inside, shut off the engine and recheck the seal and line connection.
