My fuel indicator bounces from empty to full, then may or may not stay steady on 1999 Oldsmobile Alero

What makes the fuel indicator bounce around and not keep an accurate indication of the amount of fuel in my tank?

You are likely having a problem with the float assembly of the fuel sender in the fuel tank. May be the electrical resistance feedback at the sender itself.
