        B004FMB Pull off

        Pull off the fuel tube connector cover.

      2. B004EXZC02
        *a Retainer
        *b Fuel Tube Connector
        *c Nylon Tube
        *d O-ring
        *e Fuel Pipe
        B004FMB Pinch

        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.

      3. 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 scratch or allow any foreign matter to get on the parts when disconnecting them as the fuel tube connector has O-rings that seal the pipe (fuel pipe).

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

      4. Check that there is no foreign matter on the sealing surfaces of the disconnected fuel lines. Clean them if necessary.

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