Fuel Pump: Service and Repair

FUEL PUMP AND GAUGE




Removal
1. Release fuel pressure from fuel line.
Refer to ("Fuel Pressure Release", "BASIC SERVICE PROCEDURE").
2. Remove rear seat back and bottom.
3. Remove inspection hole cover located under rear seat.
4. Disconnect connectors and fuel tubes.
5. Remove lock ring using SST KV999G0010 (J38879).




6. Remove tube plate assembly, and disconnect fuel tubes and electrical connectors.




7. Remove fuel pump by pinching the two tabs together as shown in the figure, while lifting out of fuel tank bracket.
If fuel level sensor unit needs to be removed, pull up large tab on level sensor unit, opposite the end of the float. The level sensor unit lifts straight out of fuel tank bracket.




Installation
Installation procedure is basically the reverse order of removal.

CAUTION:
- Always replace O-ring with a new one.
- Align parts with alignment marks.
- Tighten lock ring to specified torque.
- After installation, run engine and check for leaks at connections.

CAUTION:
- Always replace exhaust gaskets with new ones when reassembling.
- With engine running, check all tube connections for exhaust gas leaks, and entire system for unusual noises.
- Check to ensure that mounting brackets and mounting insulators are installed properly and free from undue stress. Improper installation could result in excessive noise or vibration.
- Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7 in) onto a hard surface such as a concrete floor; use a new one.
- Before installing new oxygen sensor, clean exhaust system threads using Oxygen Sensor Thread Cleaner tool J-43897-18 or J-43897-12 and approved anti-seize lubricant.
- Do not overtorque the oxygen sensor. Doing so may cause damage to the oxygen sensor, resulting in the MIL coming on.
