I would like fuel gauges that work, no question. But I have also

I could dip the tanks of my 182 and it was very accurate. I cannot dip
the tanks of my Bonanza due to the shape. There is a tab to determine
full tanks, 35 and 30 gallons. Less than 30 gallons there is no way to
positively know.

On our club's new Alphas there is no way at present to dip the
(single) tank so we need a fuel gauge that works. I don't know about
our aircraft but on the (slightly) older Robins I had some experience
with (same design as the Alphas) the fuel gauge senders seem to fail
with alarming regularity.

And on the older 152's we used to have the fuel gauges were all over
the show, and because the aircraft are so old, Cessna have changed the
system which would have required several thousand dollars per aircraft
to replace the whole fuel indicating system, so it was never done.
