ENGINE MOUNTED FUEL FILTER/WATER SEPARATOR
Draining Fuel/Water Separator
If the “Water in Fuel” indicator light
is illuminated and an audible chime is
heard five times, you should stop the engine and drain the water from the separator.
The drain is located on the bottom of the Fuel Filter and Water Separator assembly
which is located on the driver's side of the engine.
Turn the drain valve (located on the side of the filter) counterclockwise 1/4 turn, then
turn the ignition switch to the ON/RUN position to allow any accumulated water to
drain.
When clean fuel is visible, close the drain and switch the ignition to OFF.

drain valve 1/4 turn counterclockwise and completely drain fuel and water into
the approved container.
