Special Tools Required

Fuel sender wrench 07AAA-S0XA100

Removal

1. Relieve the fuel pressure.
2. Remove the center console.
3. Remove the access panel (A) from the floor.






4. Disconnect the fuel tank unit 4P connector (B).
5. Disconnect the quick-connect fittings (C) from the fuel tank unit.
6. Using the special tool, loosen the locknut (A).






7. Remove the locknut (A) and the fuel tank unit (B).






Installation

1. Temporarily attach a new base gasket (A) to the fuel tank unit (B), then insert the fuel tank unit partially into the fuel tank.

NOTE:
- Be careful not to damage the new base gasket.
- Be careful not to bend the fuel gauge sending unit.
- Do not coat the base gasket with oil.






2. Transfer the base gasket (A) from the fuel tank unit to the fuel tank.






3. Align the marks (B) on the fuel tank and the fuel tank unit, then insert the fuel tank unit until it sits on the base gasket.

NOTE: To prevent a fuel leak, check the base gasket, visually or by hand, to make sure it is not pinched.

4. Using the tool, tighten the new locknut (A) to the specified torque.

NOTE:
- After tightening, make sure the marks are still aligned.
- After installation, check the base gasket visually or by hand to be sure it is not pinched.

6. Reconnect the quick-connect fitting to the fuel tank unit.
7. Reconnect the negative cable to the battery, and turn the ignition switch ON (II) (but do not operate the starter motor). The fuel pump will run for about 2 seconds, and fuel pressure will rise. Repeat two or three times, and check that there is no leakage in the fuel supply system.
