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
