WARNING: Read "General Precautions" before working on the fuel system. Refer to General Precautions ".

check the fuel level with the vehicle on a level surface. If the fuel gauge indicates more than the level as shown (7/8 full), drain the fuel from the fuel tank until the fuel gauge indicates a level at or below as shown (7/8 full).
- in case the fuel pump does not operate, use the following procedure.
  1. insert fuel tubing of less than 25 mm (0.98 in) diameter into the fuel filler tube through the fuel filler opening to drain fuel from the fuel filler tube.
  2. disconnect the fuel filler hose from the fuel filler tube.
  3. insert fuel tubing into the fuel tank through the fuel filler hose to drain fuel from the fuel tank.
    - As a guide, the fuel level reaches or is less than the level on the fuel gauge as shown, when approximately 10 l (2 5/8 US gal, 2 1/4 Imp gal) of fuel is drained from a full fuel tank.

Open the fuel door and unscrew the fuel filler cap to release the pressure inside the fuel tank.
Release the fuel pressure from the fuel lines. Refer to . "FUEL PRESSURE RELEASE .
Disconnect the negative battery terminal.
Remove the center exhaust tube, with mufflers. Refer to "REMOVAL AND INSTALLATION ".
Disconnect the parking brake cables from the equalizer, then disconnect the three parking brake cable mounting brackets on each cable and position the cables out of the way. Refer to PARKING BRAKE SYSTEM , "Components".
Remove the fuel tank protector.
Disconnect the fuel filler hose, recirculation hose and EVAP canister hose at the fuel tank as shown.
Disconnect the fuel tank mounting straps while supporting the fuel tank.
Lower the fuel tank to access the top of the fuel level sensor unit, fuel filter, and fuel pump assembly.

    CAUTION:
    The tube can be removed when the tabs are completely depressed. Do not twist it more than necessary.
    
    Do not use any tools to remove the quick connector.
    
    Keep the resin tube away from heat. Be especially careful when welding near the tube.
    
    Prevent liquid acids, such as battery electrolyte, from getting on the resin tube.
    
    Do not bend or twist the tube during installation and removal.
    
    Only when the tube is replaced, remove the remaining retainer on the tube or fuel level sensor, fuel filter, and fuel pump assembly.
    
    When the tube or fuel level sensor, fuel filter, and fuel pump assembly is replaced, also replace the retainer with a new one (green colored retainer).
    
    To keep the connecting portion clean and to avoid damage and foreign materials, cover them completely with plastic bags or something similar.
