Fuel guages

Alright, I was "according to my guage" almost empty on both tanks so I went for broke and drove down to the station and filled both tanks. Strangley, they werent that empty at all, about 10 gallons to fill each tank, and when I did fill them, now my gauge reads to about 1/4 inch past full, I mean way past full, like full times two. I just got this truck and I am finding out all of its bugs. I could believe that one sending unit was bad, both BOTH units are equally defective, or so it seems. Could it just be my gauge and not the sending units? or what?
Thanks

Just for kicks check these ohm readings......

Here are the fuel guage test #s

22 ohms sent to the guage it reads empty "E"

145 ohm sent to the guage it reads full "F"

Here are the sender test #s

Sender at empty stop 14-18 ohms

Sender at full stop 154-162 ohms

Some one may have changed the tank sender for an incorrect one.........
