How far past full does the needle go. They normally go 2-3 needle widths past. If it goes way past it is probably the guage.
If the car sat for a long time with very little gas in it, the sender may have rust not allowing it to drop to the bottom of the tank.
Also, is the bottom of the tank dented in?
As long as you know where it runs out, I wouldn't worry about it.
The problem with replacing the sender is that it is in the tank with the fuel pump as an assembly.
Replacing it calls for removing the tank.
The sender/pump unit usually costs $200-$400 plus labor.
Hope this helps, VIC
