Engine Mechanical problem
2007 Jaguar XJ6 6 cyl Two Wheel Drive Automatic

One of the items on the service sheet for my 2007 Jaguar 2.7TDVi Diesel is the instruction to "DRAIN FUEL FILTER SEDIMENTOR"

I cannot find whether this is separate to one of the fuel filters or part of one of them. I also do not know where all the fuel filters are physically situated.

Is there anyone who could advise me?.
