Fuel gauges whacked

[Timcote1960]

Was flying my new bird N122wb home to DC from Boston with my wife. Beautiful WX, 2.5hr flight, 120gal aboard, burning about 10 each side according to the Shadins. Left with full fuel both gauges. By DE the needles were bouncing on zero.

I had to divert in DE to check it out. Of course, I'd only burnt 30gal. Wife was not happy, insisted she was about to die. She wasn't.

Still, it's not nice to have fuel gauges that say zero at 8,000'. What's the best solution?
