3. Pinch the fuel tubes with tube clips

to prevent fuel leakage.

4. Remove the three screws and

separate the water separator cup
from the body.

5. Thoroughly clean the water

separator cup.

6. Reassemble the water separator

body and the cup. Use a new
O-ring.

TIGHTENING TORQUE:

3.4 N·m (0.35 kgf·m, 2.5 lbf·ft)

7. Align the center of suspension

strap with the screw position and
install the water separator
assembly.

8. Reinstall the water separator in the

reverse order of removal.

9. Squeeze and release the priming

bulb to fill the vapor separator, and
check for fuel leaks. Repair any
fuel leaks if necessary.

If the buzzer sounds, water or
sediment accumulation is found to be
caused by excessive water or
sediment accumulated in the water
separator cup, inspect the fuel tank.
Clean the fuel tank if necessary.
