I calibrated the fuel tanks - a few times and it doesn't seem to work. I followed the instructions and when completed it states "fuel calbration sucessful". Right after the calibration it shows the correct amount in each tank. However when I come back a day or two later it shows one tank as completely empty despite there being several gallons of fuel or even if I add more fuel - nothing. This is a RV-9A with the standard float type fuel senders. When I calibrate I can see the values go down each time I add fuel - 2 gals at a time and recorded all values. This has happened to both tanks. It seems that when one side works the other won't. What am I doing wrong? Thanks.
