Abstract: A filter cartridge including a filter media, a first end plate including a bypass flow opening, a second end plate, and a spring tube bypass assembly. The spring tube bypass assembly includes a first center tube and a spring. The spring tube bypass assembly is configured such that fluid flow through the bypass flow opening is blocked when a fluid pressure acting on the filter cartridge is below a predetermined pressure and fluid may flow through the bypass filter opening when the fluid pressure acting on the filter cartridge exceeds the predetermined pressure.
