It's an Electronics International FL-2CA Gauge Bob. I looked on their
website and they show it but I don't see an install manual available. EI
recommends their own P-300C probes but since this was the gauge Van's
recommended for use with the RV series capacitive senders (large flat plates
mounted vertically on the ribs inside the tanks) I assume there was some
collaboration to ensure things would work. I looked through the install
manual I have and I'm afraid it doesn't say a whole lot. It shows the
pre-wired connector and identifies red, black and white wires which go to
each (right and left) sensor converter cable assembly but doesn't say what
their functions are(I assume they are power, ground and signal). The factory
bundled each of these sets of three wires with a "left" and "right" tag so
you know which is which but, that's all the information they supply.
Each sensor/converter cable assembly has five, individual, single conductor,
unshielded wires that go into what looks to me to be a tiny circuit board
about a half inch square that's covered with black heat-shrink. The three
(red, black and white) wires connect to the gauge harness mentioned above
and the other two wires connect to the senders in the tank (or the EI P-300
probe). I assume that if the wires from the tank to the converter cable CCA
needed to be shielded then EI would have provided them that way. I think
Van's just chose a BNC connection because it is very easy to drill a small
hole in the fuel tank and pro-seal the connector in (no mess, no fuss, no
leaking fuel, assuming the dielectric in the female BNC is resistant to
attack from gasoline). And the BNC is a nice positive connection well
protected from outside contamination. So... I just need to figure how mate
one of the tank sensor wires to what would be the shield crimp on a BNC male
connector. Thanks for the help.

Have an Electronics International Capacitive Fuel Gauge for Van's
capacitive senders in my RV-6 fuel tanks.......
Do you know where I can download the installation manual
for your system . . . or do you have it in .pdf form that
you can e-mail to me?
