I'm looking to replace my fuel filter on my '95 Grand Am, as preventative maintenance and also to try and get back some horsepower that is probably missing. I've had the car for 3 years, and to my knowledge it has not been changed yet. I went to look and see if I could find it under my car, and I did. But when I saw it, it looked a bit shiny and almost like it was pretty new, but the nuts that are screwed on it on the one side are pretty rusty. Just wondering if it is most likely older than the 3 years I've had it, and if they usually stay pretty non-corrosive.
