1. Check the fuel sensor. The fuel sensor is located in the fuel tank. It is a small, cylindrical device that is attached to the fuel tank with a wire. The fuel sensor sends a signal to the fuel gauge that indicates how much fuel is in the tank. If the fuel sensor is damaged or disconnected, the fuel gauge will not work properly. To check the fuel sensor, disconnect the wire from the sensor and ground the wire. If the fuel gauge reads full, the fuel sensor is working properly. If the fuel gauge does not read full, the fuel sensor is damaged and needs to be replaced.
2. Check the fuel gauge. The fuel gauge is located on the dashboard of the RTV. It is a small, round gauge that indicates how much fuel is in the tank. If the fuel gauge is damaged, it will not display the correct fuel level. To check the fuel gauge, turn on the RTV and check the fuel gauge reading. If the fuel gauge is not reading correctly, it needs to be replaced.
3. Check the wiring. The fuel sensor and the fuel gauge are connected by a wire. If the wire is damaged or disconnected, the fuel gauge will not work properly. To check the wiring, inspect the wire for damage or breaks. If the wire is damaged, it needs to be replaced.
4. Test the fuel gauge. Once you have checked the fuel sensor, the fuel gauge, and the wiring, you can test the fuel gauge. To do this, fill the fuel tank and check the fuel gauge reading. The fuel gauge should read full. If the fuel gauge does not read full, there may be a problem with the fuel gauge.
If you have checked all of the above and the fuel gauge still does not work properly, you may need to take the RTV to a Kubota dealer for service.
