Hello and welcome to JustAnswer!

The fuel gauge not working could be an issue in the cluster but there is a good chance you have a bad fuel sender or wiring issue. An open circuit on the fuel sender signal circuit will cause the gauge to drop to zero.

Did you see the cluster work correctly on the car it came out of?
