A filter element for a filter system, the filter element comprising: a tubular element extending along a longitudinal axis between a first end and a second end and defining an internal space; a retainer element associated with the first end of the tubular element, wherein the retainer element is configured to be coupled to a first housing; a valve seat member in the internal space defined by the tubular element and positioned between the first end and the second end of the tubular element, wherein the valve seat member includes a valve seat aperture configured to provide flow communication between the first end of the tubular element and the second end of the tubular element, and wherein the valve seat aperture is configured to provide a fluid seal with a valve poppet; a biasing element between the valve seat member and the retainer element, wherein the biasing element is configured to bias a coupler received from the first end of the tubular element toward the retainer element; a first end cap associated with the first end of the tubular element, wherein the first end cap defines a first end cap opening configured to provide flow communication through the first end of the tubular element; a second end cap associated with the second end of the tubular element, wherein the second end cap defines a second end cap opening configured to provide flow communication between the internal space of the tubular element and a second housing; and filter media around the tubular element and between the first and second end caps (42, 46), the filter media being configured to capture contaminates in fluid, wherein the second end cap is configured to provide a fluid seal between the filter element and a drain passage in the second housing, such that as the filter element is separated from the second housing, fluid flows from the filter element into the drain passage. a tubular element extending along a longitudinal axis between a first end and a second end and defining an internal space; a retainer element associated with the first end of the tubular element, wherein the retainer element is configured to be coupled to a first housing; a valve seat member in the internal space defined by the tubular element and positioned between the first end and the second end of the tubular element, wherein the valve seat member includes a valve seat aperture configured to provide flow communication between the first end of the tubular element and the second end of the tubular element, and wherein the valve seat aperture is configured to provide a fluid seal with a valve poppet; a biasing element between the valve seat member and the retainer element, wherein the biasing element is configured to bias a coupler received from the first end of the tubular element toward the retainer element; a first end cap associated with the first end of the tubular element, wherein the first end cap defines a first end cap opening configured to provide flow communication through the first end of the tubular element; a second end cap associated with the second end of the tubular element, wherein the second end cap defines a second end cap opening configured to provide flow communication between the internal space of the tubular element and a second housing; and filter media around the tubular element and between the first and second end caps (42, 46), the filter media being configured to capture contaminates in fluid, wherein the second end cap is configured to provide a fluid seal between the filter element and a drain passage in the second housing, such that as the filter element is separated from the second housing, fluid flows from the filter element into the drain passage.
