<<..I was also told it is best to have as much straight hose as possible on
each side of transducer..>>

I can certainly understand the need for a straight run to the inlet side,
but I don't see any reason to be too concerned about the configuration of
the downstream side.  From a normal convention, 10 diameters is often
considered to be a "long" run, so for a -6 hose that would be about 4 inches
and I would think a gentle curve as in a hose would suffice as being
"straight."  Also, I remember reading that the pressure drop through the
unit is substantial, in the range of 1 psi.  I would be reluctant to put
that kind of pressure drop in the suction sided of the mechanical pump,
especially for larger engines.  The question I have, since I am about to
mount my transducer, is about vibration.  There is no caution about
vibration levels, but just to make sure I'm mounting mine suspended by the
hoses, which are clamped to the engine inlet tubes (Lycoming).  Anyone
experienced a vibration problem, either regarding accuracy or durability?
