Hello, my name is \*\*\*\*\* \*\*\*\*\* thank you for using just answer. The site will prompt a phone call, but that is not always necessary. If it is necessary later in the conversation, I will propose it. I am sorry you are having this concern, but I will do my best to assist you. This is most likely a fault within the cluster itself. The best way to verify that would be to do a gauge sweep, which is a output test with a scan tool, or check the resistance of the fuel level circuit at the back of the cluster with a ohm meter. Hope this helps, thank you. Kyle S.
