Abstract: A filter element, for use filtering liquids such as fuel, includes a first section of filter media, an optional layer of coalescer media, and a section of barrier media. The first section and optional coalescer filter media are held between opposite first and second end caps. The second end cap is integrated with the barrier filter media. The barrier media extends at least part way into an interior of the first section and can be conical in shape.

Abstract: A fluid filter element for use in fuel filtration systems is disclosed. The filter element comprises, in an example embodiment, top and bottom end caps; filter media extending between the end caps and forming a central volume between the end caps; and an inner liner disposed in the central volume of the filter media between the end caps. A fluid passage is positioned in the inner liner extending between the end caps, the fluid passage being separate and independent of the flow through the filter media. A first seal is affixed to the bottom end cap; and a second seal with a central opening is affixed to the lower end of the inner liner. The inner lining may provide partial axial support to the filter media. An outer lining may also be included and provide partial axial support to the filter media.
