Drain Valve At Fuel Filter/water Separator
Draining water from filter canister:
The canister drain valve serves two purposes. One is to partially drain filter canister of excess water. The other is to completely drain canister for
filter, heater or water-in-fuel sensor replacement.
The filter should be drained whenever water-in- fuel warning lamp remains illuminated. (Note that lamp will be illuminated for approximately two
seconds when ignition key is initially placed in ON position for a bulb check).
