1. A jet fuel filter assembly, comprising:
an elongated filter cartridge having a top, a bottom, a length extending from the top to the bottom, an exterior, an interior, and a diameter, the filter cartridge comprising a material having a plurality of pores, the filter cartridge formed to separate water from jet fuel entering the bottom of the filter cartridge; and
a filter element residing in only a bottom region of the filter cartridge, the filter element comprising:
a hollow tube member comprised of a durable material having a top, a bottom, a length extending from the top to the bottom, an interior wall, an exterior wall, and a diameter less than the diameter of the filter cartridge; and
a plurality of flow vanes extending from the interior wall of the hollow tube member toward a center of the hollow tube member,
wherein the plurality of flow vanes are positioned within the filter element to direct the jet fuel entering the bottom of the filter cartridge in a helical path through the filter element and upward toward the top of the filter cartridge, thereby reducing pressure of the jet fuel as the jet fuel travels through the filter cartridge from the bottom of the filter cartridge to the top of the filter cartridge,
wherein the durable material of the filter element is formed to physically block the plurality of pores in only the bottom region of the filter cartridge.
