• Relieve fuel pressure at the fuel system service point before disconnecting lines.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Disconnect battery and relieve fuel pressure

• Use a 10mm socket to disconnect the negative battery cable.
• Relieve fuel pressure at the fuel system service point, then wrap the fitting with a shop towel.
• Crank only after pressure is relieved.

Step 2: Raise and support the truck

• Use a floor jack and jack stands to raise and support the Tacoma safely.
• Keep the rear of the truck stable so the fuel tank can be lowered straight down.

Step 3: Disconnect filler neck and tank connections

• Use a flat blade screwdriver and pliers to loosen the filler neck clamps and vent hose clamps.
• Disconnect the evaporative and vent hoses from the tank.
• Use a fuel line disconnect tool to separate the fuel supply line from the top of the tank assembly.
• Support the lines so they do not kink.

Step 4: Support the fuel tank

• Place a transmission jack or wide-support jack under the tank.
• Position a block or pad so the tank is held flat and secure.

Step 5: Remove fuel tank straps

• Use a 14mm socket and ratchet to remove the fuel tank strap bolts.
• Lower the tank slowly while checking for any remaining wiring or hoses.
• Remove the tank from under the vehicle once all connections are free.

Step 6: Replace the fuel pump assembly

• Clean the top of the fuel tank with shop towels before opening it.
• Disconnect the electrical connector and fuel lines from the pump module.
• Remove the lock ring carefully. Use a flat blade screwdriver if needed, but do not strike it hard.
• Lift out the old fuel pump assembly.
• Install the new fuel pump module seal and set the new pump assembly in place.
• Reinstall the lock ring and make sure it is fully seated.

Step 7: Reinstall the fuel tank

• Raise the tank with the transmission jack and reconnect all hoses and electrical connectors.
• Reinstall the fuel tank straps using a 14mm socket.
• Torque to 39 Nm (29 ft-lbs) for the tank strap bolts.
• Reconnect the fuel line using the fuel line disconnect tool until it clicks in place.

Step 8: Reconnect filler neck and battery

• Reattach the filler neck and vent hoses using a flat blade screwdriver and pliers.
• Reinstall any shields or brackets removed earlier with the 10mm socket.
• Reconnect the negative battery cable using the 10mm socket.

Step 9: Prime and check the system

• Turn the key to ON for 5 seconds, then OFF. Repeat 2-3 times to prime the system.
• Start the engine and inspect the tank, lines, and top of the pump for leaks.
• Listen for the pump before starting.

• Check for fuel leaks with the engine running and again after shutdown.
