I have a capacitive gauge and I found it way more accurate then the Belite I tried. One drawback is that it can be calibrated for either auto fuel with ethanol or no ethanol fuel, any mix will be WAY off. Any gauge mounted in the rear of a Sonex tank will be very sensitive to pitch, the indication changes about a gallon for a 1/2 inch change in level. Zenith has a float sender that can be mounted on the back of a tank without access to the interior. I have thought of but not yet tried mounting an oops fitting in the center of the tank and moving my probe there. Being an old guy, I still find a watch and knowing your fuel flow is still the least expensive and most accurate way to go.

Hi Jerry,

What capacitive sender do you have? and what system is reading it for you?

I have the standard Sonex/Princeton system. The display is on both a GRT4000 an old 0-5 volt indicator as a backup.

Princeton Capacitance Fuel level Probe

Couldn't find anything on the Sonex web site.

Google provides some information - USA off line at the moment, so may get more later.
