I like how the kits ship with everything needed for install and the wire labeling was very helpful.

The FL-2 offers pilots digital fuel levels, with unprecedented accuracy, for dual fuel tanks. Not only does the FL-2 display each tank digitally, it also provides 90′ graphical arcs for immediate, quick reference of each tank’s level. The FL-2 can be ordered to work with resistive probes (FL-2R-12 or FL-2R-24, depending on 12 or 24 volts), capacitive probes (FL-2CA) or 0-5 volt output, (such as with some Skysports probes (FL-2V). Please be sure to specify which model you need when you order your FL-2.
The FL-2 is not STC’d for installation in a certified aircraft.
When in flight, fuel will slosh around in the aircraft fuel tanks, creating irritating readings that constantly jump around. The FL-2 has a Fuel Slosh Stabilization calibration point that averages fuel level readings, creating a much more stable, but still extremely accurate fuel reading. Calibrate between a couple of seconds all the way up to over a minute of fuel slosh averaging.
The FL-2 allows installers to program from as little as two all the way up to nine fuel level calibration points in the fuel tank. This flexibility eliminates inaccuracies due to non-linear fuel tanks.
The FL-2 is a simple instrument to install and program. Clear step-by-step instructions make programming the instrument easy to calibrate to your fuel tank senders.
The pilot can easily select between displaying fuel level in Liters, Gallons or Lbs with a switch on the front of the instrument panel.
