As far as keeping the prime.. The pump will not let fuel thew unless powered up. Again acting like the solenoid.
Thoughts to ponder?
If the pump didn't turn on until switch over you would never get ignition....
Your ignition fuel goes through a different valve to get the fire started and go into preheat. It's not until switch over(half way through the start) does the main fuel valve open to finish the start and run.
