The gauges are typically at least accurate enough to alert you to a
large leak, which is a warning that your flow calculations cannot give
you. That makes the gauges useful (and operable), in a limited but
important way, and explains why they're required for airworthiness.

Fuel gauges fail a lot more often than we develop significant leaks, and
fuel gauges will never be able to reassure you that you don't have small
leak causing an extreme fire hazard.

Hence, experience has taught all of us (including the FAA), that there are
much better ways to manage your fuel 99 and 44/100% of the time, than the
fuel gauges made possible by current technology.

Get over it!!

I can assure you:
if you get caught on a ramp check,
and they even notice a failed fuel gauge,
and are anal enough to stick you for it,
and they can prove that it didn't just happen,

It just wasn't your day to be flying, and you are probably damn lucky you
didn't actually get in the air.

These are the kind of days you get run over by an F-16, loose both mags over
water, stroke out, your dog leaves you, etc. You should actually be glad
you only got stuck with 90 day suspension for a bad fuel gauge.
