Abstract: A filter assembly has a qualified filter element that filters fuel, a filter housing for the qualified filter element and a water-in-fuel sensor that senses presence of water in the filter housing. An electrical resistance of the water-in-fuel sensor changes based upon whether the qualified filter element is installed in the housing. A filter assembly can also have a plurality of magnetic elements disposed on at least one of the filter housing and the qualified filter element. A plurality of wires are disposed on at least the other of the filter housing and the qualified filter element. The control circuit determines that the qualified filter element is installed in the filter housing based on a change in the electrical current in the plurality of wires.
