  Q: How to replace the fuel pump/fuel gauge sending unit in a Toyota 4Runner?

  A: 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.

  Q: How to remove the fuel pump/fuel gauge sending unit from the tank?

  A: First of all, in 2003 and 2004 V8 Models, remove the Fuel Tank, detach the vapor pressure sensor, and disconnect the Fuel Level Sensor electrical connector. Then, release the lock tab to slide off the sending unit from the pump sub-tank. Use four screwdrivers to disengage the snap claws. Disconnect the fuel pump's electrical connector, release snap claws securing the pump to the filter assembly, and remove the pump. Inspect and remove the fuel pump outlet O-ring along with the spacer. Pry off the retaining clip and remove the pump inlet filter. The reassembly process is the reverse of disassembly. In 2005 and later V8 models, remove the fuel tank, the fuel gauge sending electrical connector, and remove the fuel gauge sending unit. Disconnect the fuel pump electrical connector, detach the suction filter hose, and separate tubes from the clamps on the suction plate. Disengage snap-claws securing the lower suction plate, and separate the suction plates and the fuel filter. Disengage snap-claws, remove the fuel pump and pump inlet filter, disconnect the fuel pump electrical connector, remove the O-ring, and inspect it. Using a screwdriver, remove E-rings, the lower suction plate, and springs from the upper suction plate. Install suction plates, along with a fuel filter. The reassembly is the reverse of removal.
