Abstract: A filter assembly includes a drain port comprising a top portion and at least one surface modification along the top portion. The drain port defines an aperture therein and is alignable with an outlet port. The outlet port includes a seal member that is attachable to an end portion of the outlet port. A portion of the aperture of the drain port is sealable to the seal member when the drain port and the outlet port are aligned such that the at least one surface modification of the drain port does not abut the seal member of the outlet port, thereby creating a sealed connection between the drain port and the outlet port.

Abstract: A filter assembly comprises a filter housing defining an internal volume having an inner cross-section defining an inner cross-sectional distance, the filter housing having a base and a sidewall. A filter element is disposed within the internal volume. The filter element comprises a filter media pack at least a portion of which has an outer cross-section defining an outer cross-sectional distance that is substantially equal to the inner cross-sectional distance of the internal volume of the filter housing. A support structure is coupled to at least one longitudinal end of the filter media pack.
