Ira,
You might consider using the trays from the 914. You would have to work up some
sort of bracket or mount as the trays on the 914 are bolted to a bracket that
is attached to the intake plenum. But they would overcome the issue with the
original trays.
You can see pics of the 914 trays on my build web-site http://www.europaowners.org/N914XL
I believe there's a decent pic at the bottom of the first image page of the last
album. There are probably better pics in the engine installation section if
you want to rummage around a bit.
Hope this helps.
Good building and great flying,

Just getting around to reading old messages, and just a comment: I have a
Fuel Mizer, a relatively inexpensive fuel totalizer from Australia I
purchased 2 years ago, and I have the sensor mounted just after the electric
backup pump. I do have a fuel return, and there is a calibration process
that does the calculus on the non-linear relationships and is run over a
long enough period to make it very accurate. I would imagine your unit is
equipped with similar software, in which case there would be no worries
about inaccuracies arizing from the fuel return.

Jack,
Thanks, that's good input. I'm glad to hear that your system worked
through the calibration process OK. As you say, I suspect mine will do
the same.

Based on the earlier replies, I'm planning to put the flow sensor
between the gascolator and the fuel pump, then calibrate the Dynon to
account for the fuel return. The portion of the fuel going to the
return may not be a linear relationship, so the calibration remains
uncertain, but probably close enough for practical purposes. I'll see

I suspect the Brauniger flow sensor provides a pulsed output like
the Flowscan, but I don't know for sure. As you suggest, I'll try Dynon
and see if they have the answer.

Paul,
I have a Tecnam Sierra with a Dynon D10 engine monitor with the
Flowscan 201 sensor which is mounted in the fuel line AFTER the "return
to tank bleed" and before the lines split to each carburettor so it only
reads fuel actually being used by both . Works fine and I believe very
accurate.The Dynon counts the pulses put out by the flowmeter.I do not
know if it compatible to other flow sensing devices. You will have to
ask Dynon
