A packed up FOHE fuel side, causing cavitation and no flow, would have been bypassed by a simple gate valve in front and behind the Plug.
Electrically (solenoid) operated slaved to a pressure sensor.

Trouble with this idea is the ice would muck up the works downstream. Pressure regulators and flow metering devices have much smaller passages than the FOHE's.
