fuel gauge faulty

on a 62 invicta the fuel gauge isnt working, fixed all connection behind dash and still nothing, i took it all out and bench tested the enitre system and it all works but when i put it back in the car the fuel gauge now goes straight to full, regardless of how much fuel i have is this a bad ground on the float unit?
 
i forgot to mention, before i took out the entire system the gauge would not move at all, it going beyond full now is something new.
 
Check the grounding wire from the sending unit to the chassis of the car.
The most common problem is the wire is broken or rusty causing a bad ground.
