Correct, you do not have to remove the wheel well liner to access the fuel filter. Remove the three plastic nuts and remove the plastic cover and you have access to the fuel filter.
If you have the original fuel filter it has crimp type connectors on the fuel lines connecting to the fuel filter (4 total). I recommend replacing them with the spring loaded self adjusting type. As I recall there were two different sizes used.
You will need to jack the car up and remove the left rear tire to gain access to the fuel filter - unless you are very thin.
As always use caution!!! you are dealing with gasoline.
