      *a Retainer
      *b O-ring
      *c Fuel Tube Connector
      *d Fuel Pipe
      *e Nylon Tube
      B003ZIE Pinch
      B003Z8F Pull

      Disconnect the fuel tube sub-assembly from the fuel delivery pipe sub-assembly.


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

        Note

        Be sure to disconnect the fuel tube connector by hand.

      2. If the fuel tube connector and fuel pipe are stuck, push and pull the fuel tube connector to release it. Pull the fuel tube connector off of the fuel pipe carefully.

        Note


        • Be sure to disconnect the fuel tube connector by hand.

        • Do not allow any scratches or foreign matter to get on the parts when disconnecting them as the fuel tube connector has O-rings that seal the fuel pipe.
