WARNING: Follow the "General Precautions" before working on the fuel system. Refer to General Precaution .
NOTE: When removing components such as hoses, tubes, lines, etc., cap or plug openings to prevent fluid from spilling.
  1. Remove the fuel filler cap to release the pressure from inside the fuel tank.
  2. Check the fuel level on level gauge. If the fuel gauge indicates more than the level as shown (half), drain the fuel from the fuel tank until the fuel gauge indicates the level as shown, or less.

    • If the fuel pump does not operate, use the following procedure to drain the fuel to the specified level.
    1. Loosen the clamp and disconnect the lower end of the fuel filler hose from the fuel tank.
    2. Insert a suitable hose of less than 15 mm (0.59 in) diameter into the fuel tank through the fuel filler opening to drain the fuel.
