Just handled this and it was super easy. If you can change a light bulb you shouldn't pay a dealer to do this. I thought I'd toss in a couple words of advice for anyone trying to do this and having a snag with the clips. The first two, use a flat head screw driver to press the button all the way down. The fuel lines will come off really easy once the button is pressed, so if you're struggling to pull the line off, the button isn't pressed all the way down. It's really difficult to press the button with your finger, especially if you're wearing gloves, that's why I'd recommend the flathead. After I took the first two off, I took the filter out of the bracket to get better access to the last one. It really didn't put any stress on the line, and the line is really flexible. This was way easier than trying to press the button on that clip with it up against the car.
Also, anyone stressing about fuel pressure... I did nothing to relieve the pressure. I backed my car onto ramps and then went for it. Only dripped out, no spray. Don't bother letting it sit overnight or anything like that... it will be fine.
