      Text in Illustration
      *1 Fuel Pipe
      *2 Fuel Tube Connector
      *3 Nylon Tube
      *4 O-ring
      *5 Retainer
      A01G8AH Pinch
      A01G47H Pull

      Pinch the retainer of the fuel tube connector, and then pull the fuel tube connector off of the fuel pipe.

      Note


      • Check for foreign matter on the fuel tube around the fuel tube connector. Clean it if necessary. Foreign matter can affect the ability of the O-ring to seal the fuel tube connector and fuel pipe.

      • Do not use any tools to separate the fuel tube connector and fuel pipe.

      • Do not forcibly bend, kink or twist the nylon tube.

      • Keep the fuel tube connector and fuel pipe free from foreign matter.

      • If the fuel tube connector and fuel pipe are stuck, push and pull to release them.

      • Cover the fuel tube connector and fuel pipe with plastic bags to prevent damage and contamination.

    3. Disconnect the fuel tube sub-assembly from the fuel hose clamp.
