I mounted the flow transducer horizontally on the engine mount between the throttle body and the distribution spider (Injected 320) with nothing to cause turbulence
at the input side and I also see about 6% higher usage (sometimes it seems to be 10%).  I have no solution other than to "fake" add fuel on long trip when I get the "total fuel low" warning.  The fuel level indications for the wings and header are very accurate.

Any others out there?
