Abstract
A system for detecting a pre-fill status of a fuel filter in a fuel system includes a monitoring mechanism structured to monitor a fluid property of the fuel system indicative of priming. A control mechanism is coupled with and structured to received data from the monitoring mechanism, and outputs a signal responsive to a time to prime the fuel system that is indicative of a filter pre-fill state.
