Frank, I have what sounds like the same capacitance fuel guage. It came from
Aerodevelopments
at Kemble, but I think they have gone out of business. I was attracted
to the idea of not having to make holes in the tank, and have mounted
mine immediately behind the cockpit module going through the central tunnel and
with a short sight tube running alongside it. I guess anyone with average Europa
skills and access to alloy welding could readily make their own system as
the flanged alloy tube for the capacitance probe to sit in was the only non
stndard
bit of it. David Joyce 402

Subject: Capacitance fuel gauge installation
A number of people have asked me for more information on the capacitance gauge
installation in G-BWYD. I can't tell you the name of the manufacturer, as the
builder has forgotten it, but the device came with a tube into which the probe
fits. It is about 1" in diameter with a flange on the top to bolt the probe
onto, and it has tappings for pipe connections at the top and bottom. It is
mounted with a bracket screwed to the back of the rear baggage bay bulkhead,
just below the access panel. The fuel feed is from the second tapping on the
port side outlet fitting on the tank, (the fuel return from the pump goes to
the second tapping on the starboard side), and of course goes to the lower
fitting
on the gauge pipe, while the upper tapping on the pipe goes to the second
vent. It will only read correctly when in level flight, but this is not a
problem
as one generally fills the tank brim full on the ground. In other respects
it seems a good solution as no new holes need to be drilled in the tank, and
the probe is readily accessible.
