reach your hand down and twist....
when the engine's not too hot.
never done it any different the last 7 years, and no problems (now with 197 k miles on the clock).

I suspect this job would be similar, if not the same, as on a 944:
1. Run tank down to "E"...the less fuel in the tank, the less fuel pressure at the hose connection.
2. Back car onto ramps or put rear of car onto jack stands.
3. Disconnect battery.
4. Briefly open fuel filler cap to relieve residual pressure in tank.
5. Put hose pliers on hose coming off tank feeding fuel pump.
6. Loosen fittings on filter [17mm?], while using another wrench [19mm?] to counter-hold.
7. Remove filter, keeping finger over filter openings to prevent fuel from spilling on face.
8. Set filter aside, put new filter in place, assembly is reverse of removal.
If your in-filter fuel screen has never been changed, this would be a good time to change it. As there is no hose to pinch while replacing the screen, raise the car a bit on that side to ensure any fuel in the tank moves away from the screen opening.
I've done this several times and a screen/filter change would probably take me <30 min, from ramp roll on to roll off. First time, should take you <1 hour, with breaks for pizza and beer.

I do my fuel filter about every 20 k miles. same time as I change out my distributor *rotor.
*caps are good for 40 k miles (at least) if you don't keep the rotors in too long.

While I haven't recently looked, I suspect the fuel filter is probably on a 30k or 60k service schedule. It also depends on local fuel quality...Porsche probably errs on the side of [international] caution.
Jeff, as little as [I suspect] you drive your cars, you could probably change yours at 10-yr intervals...though, at <$50/ea, a 5-yr cycle wouldn't hurt.

I do drive my cars! I've done two PCA parades (2011 Savannah GA and 2-13 Traverse City MI) and driven to both of them!!! French lick IN next year! I also do many other Zone 1 events. What fun are they if you can't drive them?
