Why would the gas gauge in a 1974 dodge dart swinger stop working?

The gas gauge in a 1974 Dodge Dart Swinger could stop working due to several reasons, such as a faulty fuel sender unit, which is responsible for measuring the fuel level and sending that information to the gauge. Additionally, issues like broken wiring, a blown fuse, or a malfunctioning gauge can also contribute to the problem. Corrosion or poor connections in the electrical system may further impede the gauge's functionality. A thorough inspection of these components would help identify the specific issue.
