Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

Remove the rear seat cushion if applicable to access the fuel pump access panel.
Unbolt and lift the access panel to expose the fuel pump assembly.

3. Remove the Fuel Pump

Disconnect the electrical connector from the fuel pump.
Carefully detach the fuel line using a fuel line disconnect tool.
Remove the retaining ring or screws that hold the fuel pump assembly in place.
Lift the fuel pump assembly out of the tank carefully.

4. Inspect and Replace

Inspect the old fuel pump for any visible damage or wear.
Replace the fuel pump with a new one, ensuring the new pump is compatible with the RAV4.
Reinstall the fuel pump assembly into the fuel tank, securing it with the retaining ring or screws.
Reconnect the fuel line and electrical connector, ensuring they are secured properly.

5. Reassemble and Test

Replace the access panel and re-secure the rear seat cushion.
Reconnect the negative battery terminal.
Turn the ignition key to the "ON" position and listen for the fuel pump to prime.
Start the engine to verify proper operation.
