In a low wing Piper, you look over and see the fuel flowing out of the hole.
You don't need a gauge to detect that hazard. (Perhaps this is another
advantage of flying a cherokee)

I have flown airplanes with a fuel sump drain that would not close
properly. This always happened when I took a fuel sample from the
sump, so it was was easy to notice it and fix it. But if it can happen
on the ground, it could also happen during flight.

An accurate fuel gauge is long overdue in aviation. It doesn't have to
be fancy gadgetry, fuel flow integrators or capacitive sensors. One of
the experimental guys had installed a simple pressure sensor under the
fuel tank which measured the total weight of the fuel tank. While not
perfect, it was far better than anything else I have seen, including
sight gauges.
