Sheldon,
Just to confirm, when you say that your
> 480 has the ADS-B out software installed
does that mean you have the latest 2.4 software version on your unit?
I ask because I've seen discussions on ADS-B vs ADS-B+ out there, and there seems
to be confusion between the two. Version 2.3 will give you ADS-B, but to drive
an S-mode transponder for ADS-B you need 2.4.
Again, just double-checking.
Cheers,
Wade

Garmin's software that output ADS-B did not fully meet the final rule,
so they had to revise it and give it the name ADSB+. Your transponder
has to have software that accepts ADS-B+, and your GPS has to have
software to output ADS-B+. Without the plus it is not legal. So you have
to determine which software version added that protocol for both the GPS
and for the transponder.

No, the operating voltage is not a concern. The switch is rated for 2 amps
at
24 VDC. That probably equates to 3 or 4 amps at 12 volts. If an indicator
lamp
is chosen that uses less than 1 amp, it should be fine. The switch is avai
lable
as either normally open or normally closed. There is a 50-50 chance of
getting it right. The original poster probably wants the normally closed s
witch.
Another concern is selecting the correct operating temperature. And there
is the life expectancy issue when subject to the vibration of a 2 cycle eng
ine.

A tiny keychain size infra red thermometers for $12. might be more

This is probably an adaptation of the 'capacity
sensor' widely used on touch pads for manual controll
inputs. It senses a change in capacity. The two
electrodes attached to the outside of the tank form
a capacitor in which the dielectric is composed of
tank material and air.
When fuel fills up the air space, the capacitance
goes up sharply and the electronics senses this. For
metal tanks, they need to penetrate the tank wall
to get at the change in air-to-fuel capacitance.

Another option uses the Analog Devices thermocouple
conditioners in a on-off switching mode.
https://goo.gl/7ufeaL
Here's a simplified schematic . . .
Emacs!
Instead of driving a heater control relay, one could
drive an LED indicator light directly from the
signal conditioner's output . . .
This would let you connect directly to the cylinder
head with appropriate thermocouple material.

Okay, looking closer reveals that this is a
capacity fuel gaging system, not just a level
sensor. There is a whole new class of liquid level
capacity transducer products out there.
Recent developments in resolving capacity has
spawned a variety of low cost instruments that
will measure capacitance with good accuracy
down into the picoFarads territory.
There's a pretty simple methodology for using
pic/arduino DIY processors to implement your own
capacity liquid level measurement system wherein
the sensor is nothing more than a twisted pair of
wires with insulation impervious to the liquid being
sensed.
For the product cited above, the sensor is either
copper foil electrodes on the outside of the plastic
tank . . . or some analog built into the
probe.
This could be paired with a comparator that drives
a 'tank full' indicator light.

How about using this:
http://www.beliteaircraftstore.com/bingo-liquid-detector/
It was designed for this exact purchase, and Jim Wiebe (designer/owner)
created it to indicate when a specific "bingo" (low fuel) level occurred
in header tanks and in-wing fuel tanks, as a backup to the fuel gauges.
(He has some pretty terrific fuel level sensors, as well for the
experimental crowd.)
You install this detector at whatever level in the fuel tank you choose,
and it alerts you when the liquid level drops below that point. The LED
indicator is normally green when the level is above the "bingo" level,
and if/when it drops below that point, it flashes red for 10 seconds,
then goes solid red.
Installation seems dirt simple, and it seems to work with just about any
liquid. There's a video demonstrating it on that page also. Currently
on sale for $69.95.

I have a system similar to that in my RV-10. 1 in each tank at the 3 gallo
n level.
Only really use it when I want to run a tank dry. If the tank sloshes,
then I do get some false alarms when it is bumpy. I use my float gages to
alarm
at 5 gallons left.
