The first Volkswagens did not have a fuel gauge on board, the fuel level had to be measured with a ruler in the tank. Only the more luxurious versions had an electric fuel gauge, but most had to do without this luxury.
In the mid-1950s, a fuel gauge with a fuel reserve position was used on the Volkswagen Beetle. You could use the fuel reserve without stopping if the car ran out of gas, just enough to reach the next gas station. This system was used for the entry version of the Beetle until 1969.
The Karmann Ghia, type 3 and the Bus were equipped with a petrol gauge as standard from 1955 onwards, initially for most models it was a mechanical and later an electrical gauge.
The mechanical gauges are very strong, almost nothing can break. The control cable should be able to move smoothly, if this is not the case, the cause is usually internal corrosion. Since the cable cannot be replaced as a separate part, you will need to purchase a new fuel tank gauge.
The electrical meter is a weaker instrument, first look for where the problem occurred, it may also be that the float or stabilizer is defective. The simple replacement of the meter will cause the same problem again.
