Which Annunciator Lights Do You Have or Wish You Had

[David Paule]

Any idea how this can be accomplished absent of complicated circuitry. I would be very interested to learn and possibly add it to my panel. That is for the light to come on if the switched turned to ON position and pump is not running. The desired setup for me is that the failure of the added component (warning light or any other relay in between would not cause the pump to stop running)....

We'd need a fuel pressure switch, like an oil pressure switch, that works with a carbureted engine (I haven't double-checked the pressure output of the pump, though). Wired to an Arduino microcontroller along with the pump switch, the logic for turning a light red or green or off depending on conditions ought to be fairly straight-forward.

It would have no effect upon the functioning of the pump or fuel system.
