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.
