🔧 Camry - Fuel Pump Replacement

The fuel pump on your Camry is inside the fuel tank as part of an in-tank pump/module. You’ll access it from under the rear seat, disconnect the fuel lines and wiring, then swap the pump/module with a new seal so it doesn’t leak or cause low fuel pressure.

Difficulty Level: Advanced | Estimated Time: 2.0-4.0 hours

Assumption: Your Camry has the rear-seat service access panel (common on this model).

⚠️ Safety & Precautions

• ⚠️ Work outside or in a very well-ventilated area; fuel vapors are highly flammable.
• ⚠️ No smoking, no hot lights, no grinding/sparks; keep a fire extinguisher nearby.
• ⚠️ Relieve fuel pressure before disconnecting lines to prevent fuel spray.
• ⚠️ Disconnect the 12V battery negative cable before opening the tank module.
• ⚠️ Clean dirt around the pump opening; debris in the tank can damage the new pump.
• ⚠️ Use a non-ferrous tool (brass/plastic) on the lock ring if tapping; steel-on-steel can spark.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the front wheels.
• Lower the fuel level if possible; a near-empty tank reduces spill risk.
• Relieve fuel pressure:
  • Open the hood and remove the under-hood fuse/relay box cover.
  • Remove the fuel pump relay (or EFI/fuel pump fuse if equipped).
  • Start the engine and let it run until it stalls; crank 2–3 seconds more.
  • Turn the key off.
• Disconnect the battery:
  • Use a 10mm socket to remove the negative battery cable and isolate it.
• “Lock ring” = the big ring that clamps the pump into the tank.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear seat bottom cushion

• Move the front seats forward for space.
• Use a trim removal tool set to release the seat cushion clips (push in at the front edge, then lift).
• Lift the seat bottom out and set it aside.

Step 2: Open the fuel pump service cover

• Locate the metal access cover on the floor under the seat.
• Use a 10mm socket and 3/8" ratchet to remove the cover bolts.
• Torque to 5 N·m (44 in-lbs) when reinstalling.
• Use shop towels to wipe dust, then use vacuum or compressed air blow gun to clean around the pump top.

Step 3: Disconnect electrical connector and fuel lines

• Unplug the pump electrical connector by releasing the tab with a small flathead screwdriver.
• Place shop towels around the fuel line connections.
• Disconnect the quick-connect fuel line(s):
  • Use fuel line disconnect tool set as needed for the connector style.
  • Use needle-nose pliers to remove any retaining clips (if present).
  • Expect a small amount of fuel; catch it with a catch pan.
• Pull straight—don’t twist the plastic lines.

Step 4: Mark orientation and remove the lock ring

• Use a paint marker to mark the pump module position relative to the tank (helps avoid misalignment on install).
• Remove the lock ring:
  • Use a brass punch (specialty) and small hammer to tap the lock ring counterclockwise.
  • Work slowly around the ring until it releases.
• Brass reduces spark risk vs steel tools.

Step 5: Remove the fuel pump/module assembly

• Lift the module straight up carefully.
• Angle it as needed to clear the float arm (fuel level sender).
• Let fuel drain into the tank; use shop towels to catch drips.
• Remove and discard the old tank seal (O-ring/gasket).

Step 6: Install the new seal and new pump/module

• Install the new tank seal (O-ring/gasket) into the tank opening (make sure it sits flat and isn’t twisted).
• Lower the new module into the tank, guiding the float arm in without bending it.
• Align the module using your paint marker marks.

Step 7: Reinstall lock ring and reconnect lines/wiring

• Install the lock ring and tighten it fully:
  • Use the brass punch (specialty) and small hammer to tap clockwise until it seats and alignment marks match.
  • Torque to 68 N·m (50 ft-lbs) if using an appropriate lock-ring adapter tool; otherwise tighten until fully seated to the factory stop marks.
• Reconnect fuel lines:
  • Push the connector on until it clicks.
  • Install new fuel line retaining clips if your connectors use them.
• Reconnect the electrical connector until it clicks.

Step 8: Reinstall the service cover and rear seat

• Reinstall the access cover using a 10mm socket.
• Torque to 5 N·m (44 in-lbs).
• Reinstall the rear seat bottom cushion by hooking the rear, then pressing down at the front until the clips snap in.

Step 9: Restore power and prime the fuel system

• Reconnect the battery negative cable using a 10mm socket.
• Reinstall the fuel pump relay/fuse in the under-hood box.
• Prime the system:
  • Turn the key to ON (engine off) for 5 seconds, then OFF.
  • Repeat 3 times to build fuel pressure before starting.

✅ After Repair

• Start the engine and let it idle for 2–3 minutes.
• Check carefully for leaks at the pump top and fuel line connections (use a flashlight, not a work light that gets hot).
• Take a short test drive, then re-check for fuel smell or dampness under the rear seat area.
• If the engine cranks but won’t start, re-check the relay/fuse, electrical connector latch, and that the line clicked fully into place.
