      NOTE: The figure shows engine side as an example.
      • Insert fuel tube into quick connector until the top spool on fuel tube is inserted completely and the second level spool is positioned slightly below quick connector bottom end.
        CAUTION:
        • Hold "A" position in the figure when inserting fuel tube into quick connector.
        • Carefully align center to avoid inclined insertion to prevent damage to O-ring inside quick connector.
        • Insert until you hear a "click" sound and actually feel the engagement.
        • To avoid misidentification of engagement with a similar sound, be sure to perform the next step.
    3. Before clamping fuel feed hose with hose clamps, pull quick connector hard by hand holding "A" position. Check it is completely engaged (connected) so that it does not come out from fuel feed tube.
    4. Install quick connector cap to quick connector connection.
