I've been meaning to post a message about my experience with the EI
capacitance fuel gage. When I finished my plane, I had the same
symptoms as Mike Stewart as in the message below. When I would key the
mike, my left tank reading would go to empty a large percentage of the
time, but not always. The right tank would go to empty less than half
the time. The left tank sender was much closer to the base of the
antenna, so this made some sense.
I called EI to ask if there was a suggested fix (move the senders,
shield them in some way, etc.) and the guy on the phone says: "We had
the same problem with a guy in a Lancair, so we redesigned the senders
to be immune to the RF interference. I'll send you new ones, and you
send the old ones back". Sorry Mike that you are not as important to EI
as "some guy" with a Lancair, but it does appear that they have fixed
the problem. I have the new senders on the plane and recalibrated.
They are now rock solid. I love the gage now.
I purchased my gage from Vans last summer, and I must have just missed
the production of the new senders. If you have an older gage, you might
contact EI. The only visible difference that I could see is that the
new sender came with a female BNC connector on the sender and my older
version came with just the unterminated wires.

Yes,
They are easy to install, and quite accurate.
My only gripe on the Cap units is they my fuel level goes to zero when I
transmit on com. Very annoying, but I have lived with it for 1100 hours.
EI has had the unit and says this is a "common" problem. An annoying
answer also. I have done all their troubleshooting and it still drops to
zero during transmit.
Other than that, I like the fact that there are no moving parts.
Also the bnc connector that mounts to the rib should not be used. It is
not fuel proof and will deteriorate and leak. Ask me how I know.

Does anybody have any experience with Electronics International (or
Other companies) fuel gages and capacitance fuel level senders? Would
appreciate your feed back

Brandon,
That's good information regarding the EI product revision. Just one
question regarding the "sender" -- could you confirm that you are
talking about the "Capacitive to voltage converter", and not
something internal to the tank? The converters are supplied with
the EI capacitive fuel gauges, and are also sold separately in Van's
accessory catalog (P/N IE P-300C).
Thanks,
Gunter Malich
