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.

An oil fill cap for an internal combustion engine replaces a standard cap and provides separation of air and oil in a separation zone within the cap body. The cap body defines a plurality of passages therethrough, including an upstream passage, and first and second downstream passages meeting at a separation junction. The cap body defines a separation zone at the separation junction and receiving the air/oil mixture from the engine through the upstream passage, and sending separated air to the first downstream passage, and sending separated oil to the second downstream passage.

A filtration centrifuge according to a typical embodiment of the present invention includes a housing canister, a rotor assembly, a rotor shaft, a top cap, and a bottom cap. In an alternative embodiment of the present invention, the rotor assembly mounts into the canister without the use of a rotor shaft. The canister is open at both ends and the manner of connection between the top and bottom of the canister and the top and bottom caps includes all possible combinations of internal threads, external threads, and a bayonet connection.
