Abstract
A fluid filter assembly including a canister having a canister wall, a first passage and a second passage. A center tube is disposed within the canister and defines a length between a first end and a second end. The center tube includes a center tube wall having a plurality of apertures and defining a central bore, which is aligned with and is in communication with the first passage. The center tube wall includes a resilient valve seam, which extends along the length of the center tube and has a closed position and an open position. A filter element is mounted on the center tube and is disposed within the canister. When the valve seam is in the open position, the bore is in unfiltered communication with the second passage through a gap formed at the valve seam.
