How do I change the fuel filter on a 2001 buick regal 3800?

My car's acceleration has become sluggish in the last few days....and I can't remember when the fuel filter was last changed. I bought the part--now is this worth doing myself?

if you're handy with cars, sure, but being you don't know if its ever been changed you might want to take it somewhere to change it due to the fact that they rust on sometimes and can be difficult to get off
