How many ohms is the fuel gauge in a 1958 Buick Roadmaster?

The fuel gauge in a 1958 Buick Roadmaster typically operates with a resistance range of about 0 to 30 ohms when the tank is empty to full. This resistance is part of the variable resistor (or potentiometer) in the sending unit, which translates the fuel level into an electrical signal for the gauge. However, it's always a good idea to consult the specific service manual or documentation for precise specifications.
