This procedure removes and replaces the fuel pump assembly on a 2012-2017 Toyota Camry with 2.5L I4 engine by accessing the pump module through the rear seat access panel.

Warnings

Tools required

Parts

• Fuel pump assembly × 1 — Toyota OEM 77020-06300 or equivalent
• Fuel pump gasket/seal × 1 — Included with pump assembly or Toyota 77169-06010
• Access cover seal (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level ground in a well-ventilated area away from ignition sources
2. Ensure fuel tank is less than 1/4 full; if more than 1/4 full, siphon fuel to a safe container before proceeding
3. Disconnect negative battery terminal and wait at least 90 seconds to allow fuel pump circuit to discharge
4. Place fire extinguisher within easy reach of work area
5. Gather all tools, parts, and drain containers before beginning
6. Put on safety glasses and nitrile gloves

Procedure

1. 1

   Relieve fuel system pressure
   Locate the fuel pump relay in the engine compartment fuse box (check owner's manual for exact location, typically labeled EFI or FUEL PUMP). Remove the fuel pump relay. Attempt to start the engine; it should start briefly then stall as pressure is relieved. Crank the engine 2-3 more times to ensure pressure is fully released. Turn ignition off and remove key.
   ⚠️Battery must remain disconnected during this procedure after relieving pressure. Only reconnect temporarily if absolutely necessary to complete this step, then immediately disconnect again.
2. 2

   Remove rear seat cushion
   From inside the vehicle, push down firmly on the front edge of the rear seat cushion bottom while pulling upward to release the two front mounting clips. Lift the front of the cushion up and pull forward to remove it from the vehicle. Set aside in a clean area.
3. 3

   Remove fuel pump access cover
   Locate the rectangular access cover in the floor pan beneath where the rear seat cushion was located (driver's side of vehicle). Remove the Phillips screws securing the access cover. Carefully lift the access cover and seal away from the floor pan. Inspect the seal for damage and replace if torn or compressed.
4. 4

   Disconnect electrical connector
   Locate the fuel pump electrical connector on top of the fuel pump module. Press the locking tab and carefully pull the connector straight up to disconnect. Inspect connector terminals for corrosion; clean if necessary with electrical contact cleaner.
5. 5

   Disconnect fuel lines
   Identify the fuel feed line (larger diameter) and fuel return line (if equipped). Place shop towels around the connections to catch residual fuel. Using the appropriate fuel line disconnect tool, press the release tabs on the quick-connect fittings and pull the lines straight off the fuel pump module. Plug the open lines with clean shop towels to prevent contamination.
   ⚠Expect fuel spillage. Have drain pan and absorbent materials positioned to catch fuel. Do not allow fuel to contact painted surfaces.
6. 6

   Remove fuel pump lock ring
   Using the fuel pump lock ring tool (SST 09808-14020 or equivalent), engage the tool tabs into the lock ring notches. Rotate the lock ring counterclockwise to loosen. The lock ring may be tight; use steady pressure to break it loose. Remove the lock ring completely and set aside.
   ⚠Do not use a hammer and punch to remove the lock ring, as this can damage the fuel tank or create sparks. Use only the proper lock ring tool.
7. 7

   Remove fuel pump assembly
   Carefully lift the fuel pump assembly straight up out of the fuel tank opening. Tilt the assembly slightly to allow the fuel level sender arm to clear the opening. Be careful not to damage the fuel level sender float or arm. Place the assembly in a drain pan to catch residual fuel. Cover the tank opening with a clean shop towel to prevent contamination.
   ⚠The fuel pump assembly is delicate. Do not drop or impact the sender float or fuel strainer screen.
8. 8

   Remove and inspect old gasket
   Remove the old fuel pump gasket/seal from the tank opening. Clean the mating surface on the fuel tank thoroughly with a clean, lint-free cloth. Inspect for any debris, corrosion, or damage. The sealing surface must be completely clean and smooth for proper seal.
9. 9

   Prepare new fuel pump assembly
   Remove the new fuel pump assembly from packaging. Verify that the new pump matches the old pump in configuration and connector type. Install the new gasket/seal onto the fuel pump assembly, ensuring it is seated properly in the groove. Lubricate the gasket lightly with clean gasoline to aid installation.
10. 10

    Install fuel pump assembly
    Carefully lower the new fuel pump assembly into the fuel tank opening, tilting as necessary to clear the fuel level sender arm. Align the orientation marks or tabs on the pump flange with the corresponding marks on the tank opening. Ensure the gasket remains properly seated. Press the assembly down firmly until it seats against the tank.
11. 11

    Install and torque lock ring
    Place the lock ring onto the fuel pump assembly. Using the lock ring tool, rotate the ring clockwise while applying downward pressure to engage the threads. Tighten the lock ring to the specified torque of 68.0 Nm (50 lb-ft). Verify the lock ring is fully seated and the pump assembly does not rotate.
    ⚠CRITICAL TORQUE SPEC: Proper torque is essential for fuel system seal integrity. Under-torquing will cause fuel leaks; over-torquing can crack the tank flange.
12. 12

    Reconnect fuel lines
    Remove the protective shop towels from the fuel lines. Push each fuel line quick-connect fitting straight onto the corresponding fuel pump nipple until you hear and feel a distinct click. Gently pull on each line to verify it is locked in place and will not pull off.
13. 13

    Reconnect electrical connector
    Align the fuel pump electrical connector and push it straight down onto the pump module connector until the locking tab clicks into place. Verify the connection is secure by gently pulling upward on the connector.
14. 14

    Reinstall access cover
    Position the access cover seal (new or original if in good condition) onto the floor pan opening. Place the access cover over the seal. Install the Phillips screws and tighten to 4.0 Nm (3.0 lb-ft) in a cross pattern to ensure even seal compression.
15. 15

    Reinstall rear seat and restore power
    Reinstall the rear seat cushion by inserting the rear hooks first, then pushing down firmly on the front edge until both front clips engage with an audible click. Verify the seat is secure. Reconnect the negative battery terminal. Reinstall the fuel pump relay in the fuse box.

Reassembly

1. All components are reassembled during the procedure steps above
2. Ensure all electrical connections are fully engaged and locked
3. Verify rear seat cushion is properly clipped in place before use

Verification

• Turn the ignition to ON position (do not start) for 2 seconds, then OFF. Repeat this 3-4 times to prime the fuel system and pressurize the lines
• Inspect the fuel pump access area and all line connections for any signs of fuel leakage. Use a flashlight and check carefully around the lock ring seal
• Start the engine and let it idle for 2-3 minutes. Monitor for rough running, fuel odor, or check engine light
• With engine running, recheck all fuel connections for leaks. Check fuel pressure if gauge is available (should be approximately 45-50 psi at idle)
• Turn off engine and perform final inspection of access cover area for any fuel seepage
• Test drive the vehicle briefly and verify normal fuel pump operation with no unusual noises or performance issues
• After test drive, perform final leak check of all fuel system connections while engine is hot
• If any fuel leaks are detected, immediately shut off engine, relieve fuel pressure, and inspect/correct the problem before operating vehicle
