where the f#%$ is the fuel filter in a 1999 saab 9-5, 2.3??!?

i spent a couple of hours looking for it, and didn't find it!! and we're talking about saab's here so it could be under the spare tyre WHO KNOWS!! i bought this car a week ago it has 135,000 on it! if you could give me any advices on how to take care of the car to make it last another 135,000 i would really appreciate it. some people told me that its better to use sythetic oil on this cars and do the oil changes before the 3000 miles. i also heard that the oil filter of the 2003 pt cruiser turbo fits in this saab and it's 2 inches longer so it filters better the oil protecting it from the sludge or somthing like that!. i know these cars are kinda expensive to fix so i wanna avoid breaking it!
