Abstract: A fuel filtration system includes an electric pump, a filter assembly, and conduits for fluidly connecting the pump and filter assembly in series with a fuel tank to define a kidney filtration loop. The filter assembly includes a filter assembly head, including attachment openings therethrough, and a filter exchange module, including a mounting plate having externally threaded mounting connectors extending outwardly from one face thereof and internally threaded bores opening through another face thereof. In a mounted configuration, a fuel filter is threaded onto each mounting connector such that the filter is fluidly aligned with a fuel flow opening through the mounting plate, fasteners are positioned through the attachment openings and threadably received within the bores, and fuel flow passages of the filter assembly head define a flow distribution in which one pair of filters is fluidly in parallel and another pair of filters is fluidly in series.

Abstract: A fuel filtration system is provided. The fuel filtration system includes a pump configured to receive a flow of fuel from a fuel storage tank and at least one filter positioned downstream to the fuel filtration system and fluidly coupled to the pump. The fuel filtration system further comprises a recirculation loop configured to recirculate at least a portion of the fuel through the at least one filter. The recirculation loop is also configured to provide a remaining portion of the fuel to an engine during the recirculation. The remaining portion of the fuel is determined based on a fuel consumption of the engine.

Abstract: A fluid filtration system for use with an internal combustion engine includes a fluid inlet, a fluid manifold fluidly connected to the fluid inlet, and a plurality of filter elements rotatably coupled to the fluid manifold such that an order of fluid flow through the plurality of filter elements is varied according to a position of an individual fuel filter element of the plurality of fuel filter elements with respect to the fluid manifold. The fluid filtration system may be configured such that fluid flows in series through the plurality of filter elements and the plurality of filter elements is configured to be rotated such that the order of fluid flow through the plurality of filter elements is varied such that a filter element of the plurality of filter elements which was previously a final filter element in the series becomes a first filter element in the series.
