Hi friends!

My dad is having an issue with his 2004 F150. The fuel gauge has been stuck on empty and sometimes goes below empty. The low fuel light is on. I read some of the forums to him and we haven't found much of a solution. We tried doing the sweep of the gauges and it does not budge. He looked in the panel under the driver's side rail and didn't find any corrosion issues.

We're wondering where to go from here without going to a garage. PLEASE be specific!
Thank you!!
