Abstract
A fuel filtration apparatus for use in an internal combustion engine comprises an interrupter valve in a flow path from an inlet port of a filter head to a compliant filter. The interrupter valve has an open state and a closed state. In the open state a protruding member of the filter depresses a bottom end of the valve and opens the flow path when the compliant filter is connected to the filter head. The interrupter valve also has a closed state wherein the flow path is closed in the absence of the protruding member of the filter (as with a non-compliant filter).
