Would love a little help with this. I bought a Newton V9 four way duplex valve to use on my Slepcev Storch fuel system from Aircraft Spruce. It has L,R, Both and Off settings. Also has provision for returning excess fuel back to one of the wing tanks. It has total of 6 inlet/outlets. I guess I assumed it would come with a plumbing diagram showing proper fuel line hook ups. Well, I was wrong about that and their website is no help either. Anybody have any experience with these? Engine being used is a Rotax 912 uls.
