Check for a ground connection on the sending unit.  It should have one.
If it does, clean it.  If it doesn't, add one.

To test it, check its resistance at various level of fuel.  It should
be different.  Look at the wiring schematic and figure out how the gauge
works.  Grounding the gauge may cause it to read full.  Or maybe empty.
