the kubota is self priming when you open the valve. allowing the lift pump to push the fuel back to the tank via this path. with the valve open the lift pump must keep up with both supplying the burn fuel and the bypass. I keep this valve slightly open all the time because I have a supply backflow problem and the lift pump is at the engine not at the supply. I think if it runs better withthe valve open it is overcomming an airleak issue like I have.

here is a video tip from a pro
