This procedure removes and replaces the fuel pump module assembly in a 2012-2017 Toyota Camry 2.5L I4. Access is gained through the rear seat access panel.

Warnings

Tools required

Parts

• Fuel pump module assembly × 1 — Toyota 77020-06190 or equivalent
• Fuel pump lock ring gasket × 1 — Use OEM specification
• Fuel line O-rings (quick-connect type) × 2 — Use OEM specification

Preparation

1. Park vehicle on level ground in well-ventilated area away from ignition sources
2. Ensure fuel tank is less than half full to minimize spillage
3. Place fire extinguisher within immediate reach of work area
4. Disconnect negative battery cable and wait 90 seconds for system capacitors to discharge
5. Remove rear seat cushion by pushing down and forward on front edge to release clips, then lift out
6. Identify fuel pump access cover in passenger-side rear floor pan (approximately 12 inches square)
7. Clean area around access cover thoroughly to prevent contamination entering fuel tank

Procedure

1. 1

   Relieve fuel system pressure
   Start engine and allow to idle. Remove fuel pump relay (EFI MAIN relay) from engine compartment relay box while engine is running. Engine will stall within 30 seconds as fuel rail pressure drops. Crank engine for 3-5 seconds after stalling to ensure complete pressure relief. Turn ignition OFF. Fuel system pressure is now relieved.
   ⚠️This step MUST be completed before disconnecting any fuel lines. Skipping this step will cause high-pressure fuel spray.
2. 2

   Remove fuel pump access cover
   Remove the four Phillips-head screws securing the access cover plate. Carefully lift cover and set aside with screws. You will now see the top of the fuel pump module and connected fuel lines.

3. 3

   Disconnect electrical connector
   Press down on the locking tab of the fuel pump electrical connector and pull connector straight up to disconnect. Move connector away from work area to prevent fuel contact.
4. 4

   Disconnect fuel supply line
   Place drain pan under fuel line connections. Using fuel line disconnect tool, press the tool into the quick-connect fitting on the fuel supply line (larger line) while pulling the line away from pump module. Fuel will drain from line. Have shop towels ready to absorb spillage. Cap or plug the disconnected line to prevent contamination.
   ⚠Expect approximately 100-200ml of fuel to drain from supply line. Ensure drain pan is positioned correctly.
5. 5

   Disconnect fuel return line
   Using fuel line disconnect tool, disconnect the fuel return line (smaller line if equipped - some models use returnless systems) using same procedure as supply line. If your model has only one fuel line, skip this step.
6. 6

   Remove fuel pump lock ring
   Insert fuel pump lock ring tool into the notches of the lock ring. Ensure drain pan is positioned to catch fuel spillage. Turn lock ring counterclockwise using tool until ring is completely loose. Some resistance is normal for the first 1/4 turn. Carefully lift lock ring out and set aside. Inspect lock ring gasket for damage.
   ⚠Do not use a hammer and punch to remove lock ring - this can create sparks and damage the plastic ring.

7. 7

   Remove fuel pump module assembly
   Carefully tilt and lift the fuel pump module assembly up and out of the tank opening at an angle. The assembly is approximately 10-12 inches long and must be angled to clear the opening. Fuel will drain from the assembly - keep drain pan positioned underneath. Once clear, allow all fuel to drain from assembly into pan. Inspect the fuel level sender float arm - be careful not to bend it during removal.
   ⚠The fuel level sender arm and float are delicate. Bending or damaging these components will cause inaccurate fuel gauge readings.
   ⚠Expect 200-400ml of fuel to drain from pump assembly during removal.
8. 8

   Inspect fuel tank opening and gasket surface
   Using flashlight, inspect inside fuel tank opening for debris, contamination, or damage. Check gasket sealing surface on tank for corrosion, damage, or distortion. Clean gasket surface with clean, lint-free cloth if needed. Remove old lock ring gasket from tank flange and discard.
9. 9

   Prepare new fuel pump module
   Remove new fuel pump module from packaging. Install new lock ring gasket onto the fuel tank opening flange, ensuring it seats properly in the groove. Verify new O-rings are installed on fuel line quick-connect fittings on new pump module. If O-rings are not pre-installed, install new O-rings now, lightly lubricating with clean gasoline.
   ℹ️Do not use petroleum jelly or oil-based lubricants on O-rings - use only gasoline or approved fuel system lubricant.
10. 10

    Install new fuel pump module
    Carefully lower new fuel pump module into tank opening at an angle, ensuring fuel level sender float arm does not contact tank walls. Align the module so the arrow or alignment mark on top faces toward front of vehicle. Once positioned, press module down into tank opening until it seats on gasket. Verify module is fully seated before proceeding.
    ⚠Proper alignment is critical. Arrow or mark on pump module must point toward vehicle front, or fuel gauge will read incorrectly.
11. 11

    Install and torque lock ring
    Place lock ring over fuel pump module. Insert lock ring tool into notches and turn clockwise until hand-tight. Using torque wrench with lock ring tool, tighten lock ring to specified torque of 68.0 Nm (50 lb-ft). Verify lock ring is fully seated and gasket is compressed evenly around entire perimeter.
    ⚠️CRITICAL: Lock ring must be torqued to specification. Under-torquing will cause fuel leaks; over-torquing can crack the ring or tank flange.

    Connect fuel lines
    Remove caps/plugs from fuel lines. Inspect quick-connect fittings and O-rings on pump module for damage. Push fuel supply line (larger line) straight onto pump module fitting until you hear/feel a distinct click. Pull back on line to verify it is locked. Repeat for return line if equipped. Verify both connections are secure.
    ⚠️Fuel line connections MUST click and lock securely. Incomplete connection will cause fuel leak and potential fire.
13. 13

    Connect electrical connector and reinstall access cover
    Connect electrical connector to fuel pump module by pressing firmly until locking tab clicks. Tug gently to verify connection. Clean access cover and surrounding area of any fuel residue. Position access cover over opening and install four screws. Tighten screws in cross-pattern to specified torque of 4.0 Nm (3 lb-ft).

    Complete electrical reconnection and pressurize system
    Reinstall fuel pump relay (EFI MAIN relay) in engine compartment relay box. Reconnect negative battery cable. Turn ignition to ON position (do not start engine) for 2 seconds, then OFF. Repeat this cycle 3-4 times to pressurize fuel system and prime new pump. Check all fuel line connections at pump module for leaks while system is pressurized.
    ⚠️DO NOT START ENGINE if any fuel leaks are observed. Shut off ignition immediately, relieve pressure, and correct leak source.
15. 15

    Start engine and perform leak check
    Start engine and allow to idle. Immediately check all fuel connections at pump module for leaks using flashlight through access opening (cover should still be accessible). Let engine run for 2-3 minutes while monitoring for leaks. Check fuel gauge operation - needle should move from empty toward actual fuel level within 30 seconds. If any leaks are found, shut off engine immediately and repair.
    ⚠️Any fuel leak, no matter how small, must be corrected before operating vehicle. Do not drive vehicle with active fuel leak.

Reassembly

1. Once leak check is confirmed successful, reinstall rear seat cushion by hooking rear edge into floor clips and pressing down firmly on front edge until clips engage
2. Verify all tools and parts packaging have been removed from vehicle interior
3. Dispose of old fuel pump module and contaminated shop towels according to local hazardous waste regulations
4. Dispose of drained fuel properly - do not pour down drains or onto ground

Verification

• Turn ignition ON (engine off) - fuel pump should run for 2 seconds then stop, confirming pump electrical operation
• Start engine - should start normally within 3-5 seconds with no extended cranking
• Check fuel gauge shows accurate reading matching known fuel level in tank
• No fuel odor should be detectable inside vehicle or near fuel tank area
• Check for diagnostic trouble codes - no fuel system codes should be present
• Test drive vehicle through various throttle positions - acceleration should be smooth with no hesitation or fuel starvation symptoms
• After test drive, perform final visual inspection of access panel area and under vehicle near fuel tank for any signs of fuel leakage
