Hello,

It sounds like you have a faulty fuel level sending unit.
That sending unit is located on the fuel pump in the fuel tank.
It has a float attached to it, as the fuel level goes up or down the float moves with it and that displays different level on the dash.
Over time the connector for the float can stop working. Which will make the fuel level gauge on the dash to not work.

I have attached the replacement procedure for the sending unit.

Please let me know of any questions.
Thank you.
