The fuses (2) for all the protected wiring except the headlights is under the dash, more or less above the clutch pedal, part of the headlamp circuit breaker assembly. They are glass barreled and very large, easily inspected visually though better to use a meter.

The gas gauge can also show the crankcase oil level when you press the small button below the gauge to change the sender from the gas tank to the crankcase, if the oil level shows on the gas gauge when pressing that button, the dash unit is OK and the sending unit is faulty.

Most likely the cork float has failed in the sending unit, though occasionally the little bevel gear set fails from rust or corrosion. Of course other failure modes are possible, you'll probably have to drop the tank. The usual shops like Wolff Instruments can often repair the sender. If not, a while back Atwater Kent was making a reproduction. A bit of a chore to drop the tank, what with the filler neck inside the tail light casting, and the brass flex bellows in the line, very close quarters between the rear leaf spring and the side flange on the tank.
