🔧 Camry - Fuel Pump Replacement

The fuel pump on your Camry is an in-tank pump module. The job is mostly interior access work: remove the rear seat, open the service cover, swap the pump module, and reseal everything so there are no fuel smells or leaks.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• ⚠️ Work outside or in a very well-ventilated area; fuel vapors are flammable.
• ⚠️ No smoking, no open flames, and avoid sparks (don’t use a heat gun).
• ⚠️ Disconnect the 12V battery negative terminal before opening the tank access cover.
• ⚠️ Relieve fuel pressure before disconnecting fuel lines to prevent spray.
• ⚠️ Keep a fire extinguisher rated for fuel fires nearby.
• ⚠️ Hybrid note: you are not servicing high-voltage components here, but still keep tools away from orange high-voltage cables.

📋 Before You Begin

• Park on level ground, set the parking brake, and open the windows for ventilation.
• Have as little fuel in the tank as practical (less than 1/4 tank helps reduce spills).
• Disconnect the 12V battery negative cable using a 10mm socket.
• Relieve fuel pressure before opening any fuel line (steps below).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel pressure

• Open the hood and remove the under-hood fuse/relay box cover using a trim removal tool.
• Remove the fuel pump fuse/relay (layout is on the fuse box lid) using needle-nose pliers.
• Start the car and let it run until it stalls; crank for 2–3 seconds more to bleed off pressure.
• Turn everything OFF and remove the key/fob from the car.
• Fuel pressure is trapped force—this step reduces spray.

Step 2: Disconnect the 12V battery

• In the trunk area, access the 12V battery and loosen the negative terminal with a 10mm socket.
• Move the cable aside so it cannot spring back onto the terminal.

Step 3: Remove the rear seat bottom cushion

• From the rear footwell area, release the seat bottom clips by pulling up firmly (use a trim removal tool if needed).
• If your seat has retaining bolts, remove them with a 12mm socket.
• Lift the seat bottom out and set it aside.

Step 4: Open the fuel pump service cover

• Locate the round/oval access cover in the floor under the seat.
• Peel back insulation as needed using a trim removal tool.
• Remove the service cover screws with a Phillips screwdriver (or bolts with a 10mm socket, if equipped).
• Carefully lift the cover. If it’s stuck, gently pry with a small flathead screwdriver.

Step 5: Clean the area (critical)

• Use a handheld vacuum or compressed air blow gun to remove dirt around the pump flange.
• Wipe with shop towels so debris can’t fall into the tank.
• Cleanliness prevents clogged injectors later.

Step 6: Disconnect the electrical connector and fuel lines

• Unplug the pump electrical connector by releasing the tab with a small flathead screwdriver.
• Place shop towels and a plastic drip pan to catch any fuel.
• Disconnect the fuel quick-connect line: use a fuel line disconnect pick set to lift/release the plastic lock, then pull the line straight off.
• A “quick-connect” is a snap-on fuel fitting with a locking clip.

Step 7: Remove the pump lock ring

• Mark the lock ring and tank with a reference line using a non-contact inspection light to see clearly.
• Use a fuel pump lock ring wrench (specialty) with a ratchet to loosen and remove the ring.
• Lift the ring off and set it aside.
• Don’t use steel punches—sparks are a risk.

Step 8: Remove the fuel pump module

• Carefully lift the pump module straight up; tilt as needed to clear the float arm.
• Drain fuel from the module into the plastic drip pan.
• Remove the old tank seal/O-ring from the tank opening using a trim removal tool (avoid scratching).

Step 9: Install the new seal and pump module

• Install the new tank seal/O-ring onto the tank opening (make sure it sits flat).
• Install the new pump module into the tank, keeping the float arm from bending.
• Reinstall the lock ring and tighten with the fuel pump lock ring wrench (specialty) and a torque wrench.
• Torque to 68 Nm (50 ft-lbs).
• If it feels cross-threaded, stop and realign.

Step 10: Reconnect fuel line and electrical connector

• Push the fuel line onto the fitting until it clicks; tug lightly to confirm it’s locked.
• Reconnect the electrical connector until it clicks.
• Wipe any fuel residue using shop towels.

Step 11: Reinstall the service cover and rear seat

• Reinstall the service cover using a Phillips screwdriver (or 10mm socket if bolts).
• If the butyl seal is damaged, replace it so fumes don’t enter the cabin.
• Reinstall the rear seat bottom and press down to lock the clips in place.
• If bolts were removed, install with a 12mm socket and torque wrench.
• Torque to 27 Nm (20 ft-lbs).

Step 12: Restore power and prime the fuel system

• Reconnect the 12V battery negative terminal using a 10mm socket.
• Reinstall the fuel pump fuse/relay using needle-nose pliers.
• Turn the car to ON (not READY) for 5 seconds, then OFF; repeat 3 times to prime.
• Start the car and let it idle while you check for leaks at the pump top and fuel line connection using a non-contact inspection light.

✅ After Repair

• Check carefully for fuel smell in the cabin; if present, re-check the access cover seal and fuel line lock.
• Test drive for 10–15 minutes, then re-check for leaks again.
• If a check engine light appears, scan for codes (a loose connector or evap leak can trigger it).
