Does the fuel gauge not moving after refueling indicate no fuel was added?

[CooperLynn]

After refueling, the fuel gauge not moving does not indicate that no fuel was added; it will return to normal after some time. Here is more relevant information: 1. Function of the fuel gauge: The fuel gauge is used to indicate the amount of fuel remaining in the car's fuel tank. It can be either a pointer or a digital display. The fuel gauge consists of a fuel level indicator with a voltage regulator and a fuel level sensor. The low fuel level warning device is designed to illuminate immediately when the fuel in the tank falls below a certain level, alerting the driver. 2. Reasons for the fuel gauge not moving for a long time: Most often, it is due to a loose float arm in the fuel tank, causing inaccurate readings and leading to this issue. It could also be a problem with the fuel level sensor (float) inside the tank. You can try cleaning the sliding resistor of the fuel level sensor and observe if it becomes functional. If it still doesn't work, it is recommended to replace the fuel level sensor.
