draining water, securely tighten filter cup (2) to water
separator (1) with ring nut (4).
6. Open fuel cock (3).
IMPORTANT: After draining water from the water
separator, bleed air from the fuel supply system.
Bleed Air from Fuel System

and/or run roughly.
Be sure to bleed air from the system after replacing the fuel
filter or running the fuel tank dry.
Automatic bleeding device is provided on this machine.
