  Q: How to remove and install a fuel gauge sending unit and fuel pump?

  A: Relieve the system fuel pressure. Remove the Fuel Tank. Disconnect the fuel supply and return line quick-connect fittings from the fuel pump/fuel gauge sending unit module by sliding back the yellow locking retainers and pulling up on the fittings. Note how the fuel and supply lines are routed across the top of the fuel tank, then detach them from the tank. Using a suitable tool, unscrew the retainer ring. As you turn the ring, bend each locking tab to clear the locking lugs. Carefully withdraw the fuel pump/fuel gauge sending unit assembly from the fuel tank. Make sure you don't damage the fuel pump filter or bend the sending unit float arm. Remove and inspect the fuel pump/fuel gauge sending unit 0-ring. If the 0-ring is cracked, torn or deteriorated, replace it. If you want to replace either the fuel pump or the fuel gauge sending unit, proceed accordingly. If you have been experiencing fuel delivery problems, disassemble the pump assembly while the pump is removed and inspect the pump inlet strainer. Make sure that it's not clogged or damaged. If the strainer is dirty, try washing it in clean solvent. If it's still clogged, replace the pump assembly. When installing the fuel pump/fuel gauge sending unit, make sure that the locator lug on the edge of the pump mounting flange is aligned with the notch in the pump mounting ring. When tightening the retainer ring, screw it down a couple of turns, then turn it so that the alignment mark on the ring is positioned between the two arrows on the fuel tank. Installation is otherwise the reverse of removal.
