Toyota 23220-50130 Fuel Pump Assembly

To remove the fuel pump/Fuel Level Sensor, start by relieving the fuel pressure. Then, remove the fuel tank and disconnect the quick-connect fittings for the fuel lines. Before unscrewing the retainer ring, note the lock tabs and lugs. Loosen the retainer ring, pushing out each lock tab as it approaches each lug. Use a tool to unscrew the retainer ring and withdraw the fuel pump/fuel gauge sending unit assembly from the tank, being careful not to damage the pump filter or bend the sending unit float arm. Inspect and replace the O-ring if needed. If desired, replace the fuel pump or fuel level sending unit. Inspect the pump inlet strainer for clogs or damage, cleaning or replacing it as necessary. When installing the fuel pump/fuel gauge sending unit, align the locator lug on the pump flange with the notch in the mounting ring. Tighten the retainer ring by screwing it down two turns, then position the alignment mark on the ring between the two arrows on the tank. Finally, installation is the reverse of removal.
