DRAINING WATER FROM THE SYSTEM



Filtration and separation of water from the fuel is important for trouble free operation and long life of the fuel system. Regular maintenance, including draining moisture from the fuel/water separator filter is essential to keep water out of the fuel pump. To remove the collected water, simply unscrew the drain at the bottom of the WIF assembly located at the bottom of the filter separator.
