--- every 50 hours
Water separator (2) is a device to separate water from the
fuel. The float inside the case will be raised when water is
present. After the float is raised up to the water drain level
marked on the outer diameter of the case, be sure to drain
the water.
Drainage Procedure
1. Water separator (2) is located in front of the pump.
Open the right access door and secure the door with
a rod.
2. Loosen plug (3) on the top of water separator (2).
Loosen drain plug (4) on the bottom of the case to
drain the water deposited in the case.
3. After drainage is complete, be sure to tighten plugs
(3 and 4).
NOTE: After draining water mixed in the fuel, bleed air
from the fuel system. (Refer to the descriptions
on the Bleed Air from Fuel System.
In case the fuel containing more water than usual is used,
drain water by checking the water separator at shorter in-
tervals.
