REMOVE FUEL DELIVERY PIPE (for Bank 2)
1. Disconnect the No. 3 fuel delivery pipe sub-assembly from the fuel delivery pipe (for bank 2).
  CAUTION:
  - If the connector and pipe are stuck, pinch the fuel delivery pipe No. 3 by hand and push and pull the connector to disconnect it.
  - Do not allow any scratches or foreign matter on the parts when disconnecting them, as the No. 3 fuel delivery pipe joint contains the O-rings that seal the plug.
  - Do not use any tools to separate the pipe and connector.
  - Do not forcibly bend, twist or turn the nylon tube.
  - If the pipe and connector are stuck together, pinch the tube between your fingers and turn it carefully to free it. Then, disconnect the main tube.
  - Protect the disconnected part by covering it with a plastic bag and tape after disconnecting the main tube.
  - Check that the top hat cannot be pulled out.
