Faulty Fuel warning indicator

[Jeff Swearingen]

I was driving my 2020 ram 3500 with at least 1/2 a tank when my gauge went to almost zero and indicated low fuel. I knew I had half a tank and filled it to confirm how much was in the tank and to check for a leak. I took on almost exactly half a tank of gas but when I turned my truck on the indicator shows 3/4 full when I KNOW it’s 100% full. It appears my gauge is not reading about 25% of the fuel that is in the tank. Suggestions?

Its likely something with the sending unit on the lift pump or a wiring issue on the sending unit circuit

Thanks. Sounds expensive?
