SECTION III. TECHNICAL PRINCIPLES OF OPERATION
1-11. 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 plated 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 known as the interface. The liquid level gage gives a visual
indication of this interface. Automatic controls or manual controls permit the discharge of the separated water
and prevents the flow of fuel out of the filter/separator.
