Went smoothly, the calibration. The g3x GA24 is 10 volts per Garmin. (for the guy who posted last) Anyway, I see that my analog gages don't register fuel till around 6 gals, and stop registering fuel at 14 gallons. I see that with my analog fuel gages c/b out, while initially no fuel in tank, the efis showed a voltage of 1.7 V on either tank fuel sensor. With analog fuel gage c/b in, it raised this value to 3.1 V. Being that my floats did not show a reading on the analog gages until around 6 is (i'm assuming at this point) the error due to the having the analog gages wired in parallel to GA24, as it was confirmed that after adding 1 gallon increments to either tank, from zero, showed a correct curve (and respective voltage drop) on the efis calibration. At the top end, however (14 gallon area) the curve stopped and voltage value did not change. (floats have no more travel) Going to go out and fly this and manage fuel as always and confirm my suspicions. I know my analogs, when reading just on the empty peg, still have 6 gals in each tank, and will see what my efis reads. I also made a fuel dipping stick at the 10 gal mark, for each tank. If it turns out, that my efis gives inaccurate readings, or inconsistent readings, I'll tank the analogs and gut a new panel. The red cube fuel flow will also be of considerable help. I'll report back with additional findings. Take care, DM
