Abstract

Improvements to “no filter, no run” fluid filtration systems are described. In one example, a filter includes a movable pin cage that has a first pre-installation position adjacent the bottom end plate and is temporarily connected thereto by a snap connection system, and a second position adjacent the upper end plate where it performs a valve interaction function. In another example, a filter includes non-centered valve pins that are rotatable relative to an upper end plate of the filter.
