Steve,

The solenoid has two wires going to it (+/-) they come over from the control board. It appeared to me that it is either on/open or
off/closed. I don't know of any device on the Onan that would cause it to regulate pressure or flow from the tank to the pump /
carb.

I vaguely remember reading that the solenoid was added because of some Canadian rule.

Rob M.




Correct - the solenoid valve has no pressure regulating function other than: Onan off = zero fuel flow. The example was that the GMC was parked with the Onan off. Fuel was spilling from the carb.
