Hi there! From your other post I deduce you've got a diesel, so yes indeed a diesel fuel filter is right at 20,000 KILOMETERS, 12,500 miles, according to my Chrysler owners manual. It's just that on modern vehicles, which these aren't really (definitely not the petrol push rod engine!!) garages tend not to do that kind of thing - "oh they'll be ok" attitude. If you think that's bad, the oil & filter intervals for the petrol engine model, with town work stop start driving, is 3000 miles!!!! It goes to the heady heights of 7500 miles if driven more "normally". Obviously I stick religiously to that ha ha. The diesel owner guys will assist on this I'm sure, and warn of the potential follow on problems if it's not done correctly. There also appears to be a couple of locations the fuel filter may be - from memory underneath next to the tank, or in the engine bay, and you may or may not have a hand primer bulb on yours. If you don't have the hand primer it could be best to get a garage to do it for you. On my diesel 07 Galaxy it was a complete and utter git of a job to get it running again, including the help of my neighbour who has a fuel vacuum hand pump, a proper one, (he works for Ford). Like not changing brake fluid on a many years old "full" service, never heard of it being done, in fairness it's not even in the Chrysler book.
