Section Ill. TECHNICAL PRINCIPLES OF OPERATION
1-10. Technical Principles of Operation.
a. General. The filter/separator is a static device which is installed in a fuel system to remove water and solid
contaminants from the fuel. The filter/separator is normally installed between the fuel system pump and the fuel
dispensing equipment. Thus, fuel is pushed through the filter/separator by pump action.
b. Simplified Principles of Operation. Fuel enters through the inlet connection and passes through the filter
center tube and passes towards the outside of the element. Upon reaching the exterior of the element the fuel
passes through the layers of pleated paper, cotton knit and screen. The water droplets, being heavier than fuel,
fall to the bottom of the tank. As water collects in the tank, the water level rises. Clean fuel floats on top of this
water, The point at which the fuel and water meet is the interface. The liquid level gage gives a visual indication
of this interface. Manual controls permit the discharge of the separated water and prevent the flow of fuel out of
the filter/separator.
