So I am researching on converting my 9k generator to dual fuel (gas/propane) and all I see is whats considered low pressure propane. What exactly is that?
Low pressure is BBQ tanks, RV's, stoves and that kind of stuff. They use "Vapor".
Vehicles typically use Liquid because they require so much more fuel. Liquid tanks or the liquid port on a tank would have 'dip tube' to draw the liquid.
Low pressure it what you're going to most likely need/want/use for a generator.
