First of all, do not bother with fuel pressure valve or running the engine until it stalls. As you will be disconnecting the filter, a considerable amount of fuel will spill anyway ( around a glass or so ).
Just make sure it is safe, and you are not under the car ( and you do not have to be under the car for this job ).
All the fuel that was in the filter, and in the fuel rail, will spill on the ground and/or engine parts below - there is nothing you can do about it.
As I said, you do not have to do anything under the car. You will have to raise the driver's side front of the car, and take the wheel and the splash-guard off. That will give you an easy access to the filter, which is just behind the splash-guard. You do not have to take the whole guard off, just unclip the right three fasteners - that will give you the opening big enough to work with the filter.
I had to unscrew three nuts, they seem to be metric 10 size, but on my car the ones holding the whole filter assembley to the side of the engine compartment were unusual funky light aluminium fasteners that looked like ordinary nuts hollow inside and I was able to unscrew them with my hands only. The one that was holding the filter itself inside the brace was a normal metric size10 nut, and I needed a tool for that.
Unfortunately you can not take the whole assembley with a filter and a brace out because there are other hoses attached to it, but I managed to lower the filter with the brace enough so I could see it from the opening in the splash-guard and facilitate removal of the nut holding the filter in place.
Interesting, on the other 93SL I have, the brace holding the fuel filter was made out of plastic and seemed like you could pop the filter out of the brace without unscrewing any nuts.
Disconnecting the hoses was really easy with the tool that came with the filter. I did not have to remove the air filter housing as I could easily reach for the upper hose connector. The lower one was not hard either but you do not need the tool for that.
The filter I got was made in Israel by Purolator, and I paid around 13$ for it in the Advanced Auto Parts, and the tool was included. One side of the filter had a long hose with the metal part at the end, and the other side had a plastic fitting.
