8. Replace the fuel tank pump gasket with a new one.
9. While inserting the fuel tank pump and gauge assembly into the fuel tank from the service hole, connect the suction hose to the fuel tank pump and gauge assembly to install the fuel tank pump and gauge assembly to the fuel tank.| caution | - When installing the fuel tank pump and gauge assembly into the fuel tank from the service hole, be careful not to damage the gauge unit and the float. In addition, be careful that the float does not catch the suction hose inside the fuel tank.
- When installing the fuel pump and gauge assembly to the fuel tank, check that the gauge moving area moves smoothly.
