I was once told.. that the Cessna type gauges only have to be accurate when
the tank is empty.. it should tell you so.. it does not need to be accurate
at a full or partially full tank..

it should not say 1/2 when the engine coughs and sputters on an empty tank..

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?
