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.
c. Before clamping fuel feed hose with hose clamps, pull quick connector hard by hand holding “A” position.
Make sure it is completely engaged (connected) so that it does not come out from fuel tube.
d. Install quick connector cap to quick connector connection. (On
both the engine side and the vehicle side)

Install so that the arrow mark on the side faces up.
CAUTION:

Make sure that quick connector and fuel tube are
securely fit into quick connector cap installation groove.

If quick connector cap cannot be installed smoothly,
quick connector may have not been installed correctly.
Check connection again.
NOTE:
There is quick connector cap for the engine side and for the
vehicle side, and they have different shapes. The figure shows engine side as an example.

9. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Check on Fuel Leaks
1. Apply fuel pressure to fuel lines with turning ignition switch “ON” (with engine stopped). Then make sure
there are no fuel leaks at connections.
NOTE:
Use mirrors for checking on invisible points.
2. Start engine. With engine speed increased, make sure again there are no fuel leaks at connections.
CAUTION:
