914 Fuel Pump Indicator

Since the 914 engine fails without an electric fuel pump operating, I'd like some real time monitoring of the pump/s.

Wondering what the best way to do this is?

Could I just install a fuel pressure gage on the inlet side of the regulator?

I know that fuel pressure changes with throttle, but if there is a minimum number that a functional pump would produce, I can set my Dynon warning below that.

I considered warning lights, but if the pump failed and still had an uninterrupted circuit, it wouldn't help.
