Abstract
An apparatus for conditioning fluid. In one embodiment of the present invention, there is an apparatus which comprises two filters and an electrically actuatable switching valve. Fluid provided to the apparatus may be routed to either filter by the switching valve. A controller positions the valve to provide fluid to a particular filter based on a measurement of pressure downstream of the filter, provided that the temperature of the fluid is above a predetermined level. Further, the invention includes proximity switches by which the controller can determine the coupling or uncoupling of a filter from the body. Various fuel heaters are provided for heating the fuel.
