A pulse dampening interface between a filter and a filter base configured to mitigate pulses, the interface comprising: a housing bolt; a base; and a replaceable filter element that includes at least a partially cylindrical configuration and that defines a longitudinal axis, and a radial direction, the filter element comprising: an annular filter media defining a central passage; a center tube that is disposed in the central passage of the annular filter media that defines a central reservoir, and the annular filter media surrounds the center tube and the central reservoir; a top open end joined to the center tube disposed along the longitudinal axis, the top open end including an opening allowing fluid to flow from the central reservoir to the outside of the filter element; a bottom open end joined to the center tube opposite the top open end disposed along the longitudinal axis; and a filter pulsation dampening device characterised in that the filter pulsation dampening device including a movable flexible valve extending from the filter element having a valve free end that is disposed in the central reservoir of the center tube; a first baffle (226") extending from the housing bolt and terminating at a first baffle free end (240") and the flexible valve of the filter element which is disposed radially inwardly and longitudinally above the first baffle free end, defining a shut-off gap distance between the first baffle valve free end and the flexible valve, wherein the flexible valve opens and closes on the first baffle (226") and opens when there is no pressure pulsation downstream, allowing a normal flow of filtered fluid. a housing bolt; a base; and a replaceable filter element that includes at least a partially cylindrical configuration and that defines a longitudinal axis, and a radial direction, the filter element comprising: an annular filter media defining a central passage; a center tube that is disposed in the central passage of the annular filter media that defines a central reservoir, and the annular filter media surrounds the center tube and the central reservoir; a top open end joined to the center tube disposed along the longitudinal axis, the top open end including an opening allowing fluid to flow from the central reservoir to the outside of the filter element; a bottom open end joined to the center tube opposite the top open end disposed along the longitudinal axis; and a filter pulsation dampening device characterised in that the filter pulsation dampening device including a movable flexible valve extending from the filter element having a valve free end that is disposed in the central reservoir of the center tube; a first baffle (226") extending from the housing bolt and terminating at a first baffle free end (240") and the flexible valve of the filter element which is disposed radially inwardly and longitudinally above the first baffle free end, defining a shut-off gap distance between the first baffle valve free end and the flexible valve, wherein the flexible valve opens and closes on the first baffle (226") and opens when there is no pressure pulsation downstream, allowing a normal flow of filtered fluid. an annular filter media defining a central passage; a center tube that is disposed in the central passage of the annular filter media that defines a central reservoir, and the annular filter media surrounds the center tube and the central reservoir; a top open end joined to the center tube disposed along the longitudinal axis, the top open end including an opening allowing fluid to flow from the central reservoir to the outside of the filter element; a bottom open end joined to the center tube opposite the top open end disposed along the longitudinal axis; and a filter pulsation dampening device characterised in that the filter pulsation dampening device including a movable flexible valve extending from the filter element having a valve free end that is disposed in the central reservoir of the center tube; a first baffle (226") extending from the housing bolt and terminating at a first baffle free end (240") and the flexible valve of the filter element which is disposed radially inwardly and longitudinally above the first baffle free end, defining a shut-off gap distance between the first baffle valve free end and the flexible valve, wherein the flexible valve opens and closes on the first baffle (226") and opens when there is no pressure pulsation downstream, allowing a normal flow of filtered fluid.
