2003 Saturn L300 6 cyl

My Saturn L300 failed the emissions test. We put the scanner on it and the bank 1 & 2 sensors were reading high and only moving from 925 to 1025. I replaced the front one and the readings were still the same. Any ideas what might be causing this. Also, where is the fuel filter located?

The fuel filter is located on the right rear of the car, next to the fuel tank. As far as the HO2 sensors go, they could be reading high for a few reasons. Does the car drive ok, does it have as much pick up as it used to? And does the check engine light ever come on?
