Abstract

A no filter no run (NFNR) fluid filter and fluid filter assembly are provided. The NFNR fluid filter assembly includes a fluid filter, a filter head or filter housing, and a bypass flow path. The bypass flow path may be sealed off when a compliant filter is installed. When a non-compliant filter is installed (a filter without a bypass seal), fluid may flow to the bypass flow path.
