I understand that functional fuel gauges are required equipment for day VFR
flight. Yesterday during my preflight in a 172 I saw that the right gauge
was functioning intermittently--it would show full, flicker down to zero,
bounce around, etc. Tank was visually confirmed full. Mechanic messed
around with it for a while to no effect.

Would you fly this airplane?

Since we are taught from day 1 of our flight lessons to never trust the gas
gauge anyway, what difference does it make?
