Well with 110,000 miles on the original fuel filter, I'd say it's time to replace it. I already bought it, and upon looking under my car I see that it is pretty rusty. It doesn't look like it will snap off or anything crazy like that, but the outer layer that I can see is definitely getting bad. In these pictures I already have it soaked with wd-40. Should I let it soak for a few hours and then try? Maybe wait a few more days while it soaks? Or not attempt it at all? What if they break anyway, I don't know how to replace these.
