What says a fuel gauge is any more or less accurate than a fuel FLOW
gauge?

I don't see the relationship of your question to anything I posted.

I was agreeing with your counterpoint to someone else who was a FF fanatic
:~).

But
certainly in the ranges over a quarter tank, experience in small a/c show
that a properly calibrated fuel flow gauge is more accurate.

As a matter of fact, I believe that the fuel quantity indicators are only
required to be accurate at zero fuel in level flight (for a/c certified
under Part 23).

Ummm...no; they must be accurate at all fuel levels. Point is to find out
exactly what 1/2, 3/4, ...really means. I do it a couple times a year just
to verify the gauge's accuracy. It actually is off my 15 gallons on a full
tanks. (Incidentally, those are the only times my tanks are topped off. They
hold 98 gallons by the POH, but 99.5 by my measurements. Other than those
time, I've never had more than 84 gallons in them and that was for a two leg
trip of over 800nm.
