Abstract:
A filter is provided having a housing that includes a cavity. A center tube includes first and second ends spaced from one another. A seat extends radially from the center tube and is arranged between the first and second ends. A media pack is arranged within the cavity and supported on the seat such that the center tube extends through a central opening of the media pack. An anti-drainback valve is supported on the seat and is in sealing engagement with the center tube and the media pack. The housing includes a tapping plate that provides an inlet and outlet. An annular lip of the anti-drainback valve is in sealing engagement with the tapping plate when in a closed position in which the engine is shut off.
