Could be a bad sending unit or the float is stuck, my thoughts. But then again you stated that it was doing it in both tanks, take your volt meter and check the resistents at the back of the guage, or the switch. I have taken the float out and then moved it and then see what the guage does, check your grounds. Mine was always way beyond full, replaced the switch under the truck and it worked fine, hope you didn't buy the switch at auto zone.
