I must say that the fuel filter change in the S60 is the easiest I've ever done (I've done it in my 240, 850, and Toyota Tacoma).

I didn't need to jack the car up, just slid underneath the car. I didn't pull any fuses or disconnect any wiring anywhere (I did loosen the gas cap though). The filter is on the passenger just forward of the rear wheel. Once you loosen the mounting bracket the rest is pretty quick. I had minimal leakage but like KlausC said, glasses are a good idea. Also, the schrader valve were covered with tape - good idea to put on new tape to keep this area dirt free.

Entire change took less than 10 minutes.
