🔧 Camry - Fuel Pump Replacement

On your Camry Hybrid, the fuel pump is inside the fuel tank as part of an in-tank module, accessed from under the rear seat. The job is mostly careful disassembly and reassembly—cleanliness and leak-checking are the big keys.

⚠️ Safety & Precautions

• 🧯 Work outside or in a very well-ventilated area—gas fumes ignite easily.
• 🚫 No smoking, no sparks, no hot work lights; use an LED work light.
• 🧤 Wear safety glasses and fuel-resistant gloves; fuel can spray when lines open.
• 🔋 Disconnect the 12V battery negative terminal before opening the tank module.
• 🧼 Keep dirt out of the tank—clean the area before opening the pump module.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear seat cushion

• Slide the front seats forward for working room.
• Release the rear seat bottom cushion (some cushions pop up from front clips; some have bolts).
• If bolts are present, remove them using a 12mm socket and 3/8" drive ratchet.
• Lift the seat cushion out and set it aside.

Step 2: Open the fuel pump access cover

• Find the access panel in the floor under the rear seat area.
• Remove the access cover screws using a Phillips screwdriver.
• Peel back any butyl sealer carefully using a flat trim removal tool.

Step 3: Clean and mark the module position

• Thoroughly wipe/vacuum dirt around the fuel pump module using shop towels. Cleanliness prevents tank contamination.
• Use a paint marker to mark the alignment between the module and tank (helps reinstall correctly).

Step 4: Disconnect the electrical connector(s)

• Unplug the pump/module connector(s) by releasing the lock tab by hand or with a flat trim removal tool.

Step 5: Disconnect the fuel line(s)

• Wrap the connection with shop towels to catch any spray/drips.
• Release the quick-connect fitting (press the tabs and pull the line straight off). Use needle-nose pliers only if needed and gently—don’t crush the fitting.
• Let any fuel drain into a plastic catch pan.

Step 6: Remove the pump retaining ring (two common styles)

• If your Camry uses a lock ring:
• Use a fuel pump lock ring wrench (specialty) to turn the ring counterclockwise and remove it.
• If your Camry uses small retaining nuts/bolts:
• Remove them evenly in a crisscross pattern using a 10mm socket and 3/8" drive ratchet.
• During installation later: Torque to 4.0 Nm (35 in-lbs) in a crisscross pattern (do not overtighten).

Step 7: Lift the fuel pump module out

• Carefully lift the module straight up; tilt as needed to clear the float arm (the fuel level sensor arm).
• Have the plastic catch pan ready—fuel in the module will spill.
• 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 fuel pump module tank seal (O-ring/gasket) onto the tank opening (or as supplied with your part).
• Lower the new fuel pump module into the tank, keeping the float arm from binding.
• Align to your paint marker marks.

Step 9: Reinstall the lock ring / fasteners

• Lock ring style: Start the ring by hand, then tighten using the fuel pump lock ring wrench (specialty) until fully seated and aligned.
• Nut/bolt style: Tighten in a crisscross pattern using a 10mm socket, then Torque to 4.0 Nm (35 in-lbs).

Step 10: Reconnect fuel line(s) and electrical

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

Step 11: Reinstall the access cover and rear seat

• Reinstall the access cover using a Phillips screwdriver.
• Reinstall the rear seat cushion (and any bolts) using a 12mm socket and 3/8" drive ratchet.

Step 12: Reconnect the 12V battery

• Reconnect the negative terminal using a 10mm socket.

✅ After Repair

• Turn the car to READY and let it sit for 10–20 seconds to allow the system to pressurize.
• Check carefully for fuel smell or wetness at the line connection and around the module opening.
• If you have a check engine light, scan and clear codes after confirming there are no leaks.
• Take a short test drive, then re-check for leaks again.
