How do you change the fuel filter and is it hard or costly on a 1997 Lincoln Mark VIII?

It's in the passenger side wheel well, you have to take out the wheel well liner and it is right there. It's a lot easier than the first generation Marks and the filter should be around $12.00. Some people might say to get it from under the car but look first and you decide. My Ford dealer (good friend of ours) suggested it was way past time for my 98 Mark 8 to get it's first fuel filter replacement. I was charged $51.09 which included the part $22.11 and labor and tax. I was very satisfied with the work.
