Good Evening Peter,
Once upon a time in a land far, far, away, I knew a fella that fitted a "T" fitting in the outlet of his left fuel tank on a Cessna 170. From that fitting he ran a one eighth inch hunk of brass tubing to a small needle valve mounted on the instrument panel. From that valve to the throat of the stock Marvel Schebler carburetor he ran another hunk of brass tubing. Not sure about the size of the tubing and fitting used here. That was inserted into a stock fitting that was screwed into the side of the throat of the carburetor.
My recollection fails me here, but I believe he had bored a hole just above the throttle valve plate to accommodate the fuel fitting. Not sure though.
In any case, he could turn the fuel valve to off, turn on the needle valve, adjust the throttle plate and get a rather nice smooth running engine. He had added that extra fuel source after having had a stock gascolator get plugged with crud such that no fuel was available to the engine from either fuel cell.
Strictly illegal, but pretty neat!
Happy Skies,
Old Bob

Your set up sounds good. I am interested in your manual valve back up and
would be happy for any details. I looked at the possibility of using a
carburetor as a throttle body but gave up with the aerocarb because it jams.
A suitable butterfly carb would be an option but I like your idea.

Peter, Bob just answered for me better than I ever could have.
For me, this provides redundancy where I loose the injectors, injector
controller or the electron pump. I will be able to switch off the fuel
pump (a 6A load) to conserve battery.
