  3. FUEL SYSTEM 
    1. When disconnecting the high-pressure fuel line, a large amount of gasoline will splash. So take the following precautions:
      1. Discharge the fuel system pressure.
      2. Disconnect the fuel tube (See ON-VEHICLE INSPECTION  ).
      3. Release the pressure remaining in the fuel tank main tube.
      4. Cover the disconnected fuel tank main tube (fuel tube joint and fuel tube connector) with a vinyl bag to prevent damage and the intrusion of foreign objects.
      5. Put a container under the connection.
