Removal and Installation: Removal

WARNING: This page is about a different car, the 2012 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Follow the "General Precautions" before working on the fuel system. Refer to "GENERAL PRECAUTION ".
  1. Remove the fuel filler cap to release the pressure from inside the fuel tank.
  2. Remove the LH rear wheel and tire. Refer to "ADJUSTMENT ".
  3. Check the fuel level on level gauge. If the fuel gauge indicates more than the level as shown (full or almost full), drain the fuel from the fuel tank until the fuel gauge indicates the level as shown, or less.
    NOTE: Fuel may be spilled through the fuel tank filler hose fitting when lowering the fuel tank if the level is above "1/2".
    • As a guide, the fuel level reaches the fuel gauge position as shown, or less, when approximately 43 l  (11 3/8 US gal, 9 1/2 Imp gal) of fuel is drained from a full fuel tank.
    • If the fuel pump does not operate, use the following procedure to drain the fuel to the specified level.

    1. Insert a suitable hose of less than 15 mm (0.59 in) diameter into the fuel filler pipe through the fuel filler opening to drain the fuel from fuel filler pipe.
    2. Disconnect the fuel filler hose from the fuel filler pipe.
    3. Insert a suitable hose into the fuel tank through the fuel filler hose to drain the fuel from the fuel tank.
  4. Release the fuel pressure from the fuel lines. Refer to "FUEL PRESSURE CHECK " (VQ40DE), "FUEL PRESSURE CHECK " (VK56DE).
  5. Disconnect the battery negative terminal.
  6. Disconnect the lower fuel filler hose from the fuel tank, the EVAP hose, and the vent pipe quick connector.
    • Disconnect the fuel feed hose from the molded clip in the side of the fuel tank.

    Disconnect the quick connector as follows:

    • Hold the sides of the connector, push in the tabs and pull out the tube.
    • If the connector and the tube are stuck together, push and pull several times until they start to move. Then disconnect them by pulling.
    CAUTION:
    • The quick connector can be disconnected when the tabs are completely depressed. Do not twist the quick connector more than necessary.
    • Do not use any tools to disconnect the quick connector.
    • Keep the resin tube away from heat. Be especially careful when welding near the tube.
    • Prevent any acid liquids such as battery electrolyte, from getting on the resin tube.
    • Do not bend or twist the resin tube during connection.
    • Do not remove the remaining retainer on the hard tube (or the equivalent) except when the resin tube or the retainer is replaced.
    • When the resin tube or hard tube, or the equivalent, is replaced, also replace the retainer with a new one (semitransparent colored retainer).
