Toyota 23220-16190 Fuel Pump Assembly

1988 through 1990 models do not have an access hole for fuel pump removal, so the fuel tank needs to be removed to gain access to the fuel pump. On 1991 and later models, the middle seat needs to be removed to uncover the fuel pump access cover for fuel pump testing and replacement procedures. To remove the fuel pump, first relieve the fuel system pressure and disconnect the cable from the negative terminal of the battery. On 1988 through 1990 models, remove the fuel tank from the vehicle. On 1991 and later models, remove the middle seat and lift off the fuel pump/sending unit access cover. Disconnect the electrical connector and fuel lines, and remove the fuel pump/sending unit retaining bolts. Carefully withdraw the fuel pump/fuel level sending unit assembly from the fuel tank, making sure not to damage the inlet screen or float arm. Pry the lower end of the fuel pump loose from the bracket and remove the rubber cushion. Remove the clip securing the inlet screen to the pump and inspect the screen for contamination. If dirty, replace it. If only replacing the fuel pump inlet screen, install the new screen, clip, and rubber cushion, and push the lower end of the pump back into the bracket. If replacing the fuel pump, remove the hose clamp at the upper end of the pump and disconnect the pump from the hose. Disconnect the wires from the pump terminals and remove the pump. Installation is the reverse of removal, making sure to use new sealing washers on either side of the banjo fitting if applicable, and tighten the fitting bolt.
