A fluid filter assembly for filtering a fluid includes a housing base portion having an axially extending tube, a housing cover that is connected to the housing base portion to define an interior space, a filter element, and an interface structure. The filter element is disposed within the interior space and in engagement with the axially extending tube, the filter element having a filter media, a bottom end cap, a top end cap, and a mounting member defined by the top end cap, the mounting member having an axial wall with a vent passage therethrough and a radial wall that encircles the axial wall. The interface structure is connected to the housing cover and engages the top end cap of the filter element.

1. A fluid filter assembly for filtering a fluid, comprising: a housing base portion having an axially extending tube;a housing cover, wherein the housing cover is connected to the housing base portion to define an interior space;a filter element disposed within the interior space and in engagement
1. A fluid filter assembly for filtering a fluid, comprising: a housing base portion having an axially extending tube;a housing cover, wherein the housing cover is connected to the housing base portion to define an interior space;a filter element disposed within the interior space and in engagement with the axially extending tube, the filter element having a filter media, a bottom end cap connected to the filter media, a top end cap connected to the filter media, and a mounting member defined by the top end cap, the mounting member having an axial wall with a vent passage therethrough and a radial wall that encircles the vent passage; andan interface structure that is connected to the housing cover and serves as an interface between the interior space and the filter element, the interface structure having an annular engaging part that defines a central opening, wherein the interface structure engages the top end cap of the filter element such that the vent passage of the mounting member is disposed within the central opening of the interface structure to create a fluid communication channel between the central opening, the vent passage, and the axially extending tube. 2. The fluid filter assembly of claim 1, wherein the housing cover defines a threaded opening, the interface structure includes a threaded portion, and the interface structure is connected to the housing cover by threaded engagement of the threaded opening of the housing cover with respect to the threaded portion of the interface structure. 3. The fluid filter assembly of claim 2, wherein the interface structure includes a knob portion that is disposed outside of the housing cover. 4. The fluid filter assembly of claim 1, wherein the interface structure engages the top end cap of the filter element via a non-threaded engagement. 5. The fluid filter assembly of claim 1, wherein the annular engaging part of the interface structure is in engagement with the top end cap of the filter element. 6. The fluid filter assembly of claim 1, wherein engagement of the filter element and the annular engaging part of the interface structure urges the filter element into engagement with the housing base portion. 7. The fluid filter assembly of claim 1, wherein the interface structure includes an annular sealing member that is in engagement with the top end cap of the filter element. 8. The fluid filter assembly of claim 1, wherein the top end cap includes a base surface that encircles the mounting member, and the annular engaging part of the interface structure is in engagement with the base surface of the top end cap. 9. The fluid filter assembly of claim 1, wherein the top end cap includes a trough that encircles the mounting member, and the annular engaging part of the interface structure is in engagement with the trough of the top end cap. 10. The fluid filter assembly of claim 1, further comprising: a pressure relief valve disposed in the vent passage of the mounting member of the top end cap of the filter element. 11. The fluid filter assembly of claim 1, further comprising: a pressure relief valve disposed in the interface structure for selectively preventing or allowing the fluid and/or air/vapor to pass therethrough. 12. The fluid filter assembly of claim 1, further comprising: the interface structure including an interface housing having an upper interior portion in communication with an exterior of the filter element and a lower interior portion that is in communication with an interior of the filter element and is sealed with respect to the filter element; anda pressure relief valve in communication with the upper interior portion and the lower interior portion of the interface housing of the interface structure for selectively allowing the fluid and/or air/vapor to pass therethrough from the upper interior portion to the lower interior portion. 13. The fluid filter assembly of claim 1, wherein the housing cover defines a threaded opening, the interface structure has an upper portion that is threadedly connected to the threaded opening of the housing cover, the interface structure has a lower portion with the annular engaging part defined thereon, and the lower portion is connected to the upper portion for rotation in unison therewith when the torque applied to the upper portion is less than a predetermined torque value and for slipping with respect to the upper portion when the torque applied to the upper portion is greater than a predetermined torque value. 14. The fluid filter assembly of claim 1, wherein the mounting member includes a plurality of arcuate walls that extend from the axial wall of the mounting element and encircle the vent passage, wherein gaps are defined between adjacent pairs of the arcuate walls. 15. The fluid filter assembly of claim 1, further comprising: a divider that is connected to the housing cover and is positioned inside the housing cover, the divider having an upper end that is sealable with respect to the top end cap of the filter media to define an inner portion of the interior space between the divider and filter element and an outer portion of the interior space between the divider and the housing cover. 16. The fluid filter assembly of claim 15, wherein the divider includes a plurality of spacing structures that connect the divider to the housing cover. 17. The fluid filter assembly of claim 16, wherein the spacing structures are ribs. 18. The fluid filter assembly of claim 15, wherein the divider is fabricated from an opaque material to block visibility of a fluid level in the inner portion of the interior space. 19. A fluid filter assembly for filtering a fluid, comprising: a housing base portion having an axially extending tube;a housing cover having a threaded opening, wherein the housing cover is connected to the housing base portion to define an interior space;a filter element disposed within the interior space and in engagement with the axially extending tube, the filter element having a filter media, a bottom end cap connected to the filter media, a top end cap connected to the filter media, and a mounting member defined by the top end cap; andan interface structure having a upper portion that is threadedly connected to the threaded opening of the housing cover, a lower portion that is engageable with the mounting member of the top end cap of the filter element, and an interface ring having passages extending therethrough, wherein the lower portion is connected to the upper portion for rotation in unison therewith when the torque applied to the upper portion is less than a predetermined torque value and for slipping with respect to the upper portion when the torque applied to the upper portion is greater than a predetermined torque value, and wherein a fluid communication channel extends between at least the interior space, the passages of the interface ring, and the axially extending tube.
