[V8] Fuel never reads Full

[S_Matus]

Has anyone been able to fill your fuel cell to read on the mark right past the "20" indication in the fuel gauge?  I have tried to overfill but it does not dgo up that far.  I'm cautious not to damage the emmissions on the car.
 
Could it be a connection issue in the cluster?
 
THanks,
