      2. Drain any fuel remaining inside the fuel tube.

      3. To protect the disconnected fuel tube from damage and contamination, cover it with a plastic bag.

      4. Put a container under the connection.

    2. Perform the following procedure when disconnecting the fuel tube connector (quick type A).

        *a Fuel Tube Connector Cover
        B0068HS Pull

        Remove the fuel tube connector cover.

      2. Check whether there is any foreign matter on the fuel pipe around the fuel tube connector before disconnecting it. Clean it if necessary.

      3. A01L93CC05
        *a Retainer
        B0068HS Pinch
        B006964 Pull Out

        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.

      4. A01LD8VC01

        *b Nylon Tube
        *c Fuel Pipe
        *d O-ring
        *e Fuel Tube Connector

        If the fuel tube connector and the fuel pipe are stuck, push in and pull on the fuel tube connector to release it. Pull the fuel tube connector out of the fuel pipe carefully.

        Note


        • Check for any dirt and foreign matter contamination in the fuel pipe and around the connector. Clean if necessary. Foreign matter may damage the O-ring or cause leaks in the seal between the fuel pipe and fuel tube connector.

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

        • Check for any dirt and foreign matter on the fuel pipe seal surface. Clean if necessary.

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

        • Protect the disconnected part by covering it with a plastic bag and tape after disconnecting the fuel tube.

        • If the fuel pipe and fuel tube connector are stuck together, pinch the connector between your fingers and turn it carefully to free it. Then disconnect the fuel tube.

      5. Check that there is no foreign matter on the sealing surfaces of the disconnected fuel pipes. Clean the surfaces if necessary.

      6. Cover the disconnected fuel pipe and fuel tube connector with a plastic bag to prevent damage and contamination.

    3. Perform the following procedure when connecting the fuel tube connector (quick type A).


      1. Check if there is any damage or foreign matter on the connecting parts of the fuel pipe.

      2. A01LF32

        Line up the 2 parts of the fuel lines to be connected, and push them together until the fuel tube connector makes a "click" sound. If the fuel pipe is difficult to push into the fuel tube connector, apply a small amount of clean engine oil to the tip of the fuel pipe and reinsert it.

      3. A01L94O

        After connecting the fuel lines, check that the fuel pipe and fuel tube connector are securely connected by pulling on them.

      4. Inspect for fuel leaks.
