Guys, here's another opinion... I wouldn't mount the flow sensor anywhere
attached to the engine, I believe the vibration will destroy (did in my
case) the tiny fragile jeweled turbine bearing inside it. Although on a
carbureted engine, check toward the bottom of this page for my experience...

I used a rubber line from the servo up between #1 and #3 cylinders with a
gentle 90 degree curve (which I was told would be okay) to the flow transducer.
Out of the transducer I made a special 90 degree fitting to go directly into
the flow divider. It seems to work fine and very simple to do. I put a small
bracket to one of the case center bolts to help support the transducer. Give
me a call if you need more details. My phone # is 317-718-3415. Jim Winings
