FUEL FILTER SENSOR

Purpose
The fuel filter water sensor activates when too much
water has accumulated in the water separator fuel filter.
A warning light on the control panel indicates the need
for fuel filter service.
Location
The fuel filter, with the fuel filter sensor, is located under
the seat, on the left side of the unit. The fuel filter sensor
is located under the fuel filter (Fig. 383).

How It Works
The fuel filter sensor is a float type switch. Water is
heavier than fuel and when water accumulates in the
base of the sensor, a float raises and closes off a set
of contacts. This completes the ground to the indicator
light located on the control panel (Fig. 384).
