Abstract
A filter, filter element and filter assembly are provided. The filter includes a water separating device for separating water from a dirty fluid flow. The water separator includes a fluid flow path that varies in cross-sectional area to vary pressure of the fluid therethrough. A top portion of the water separator is formed as a structurally independent piece from a bottom portion of the water separator. The top portion may be permanently or releasably secured to filter media of the filter via an end cap coupled to an end of the filter media. The bottom portion may be integrally or releasably secured to a housing of the filter. The bottom portion may also be integrally formed with a center tube upon which a filter element mounts.
