well once a while ago while working on my 2004 2.5t s60 i saw the fuel filter
now i cant seem to find it again, i got the part but where to put it is the issue
thanks for the help

 

well in case anyone is wondering in the United States the filter is just forward of the fuel tank in front of the right wheel and in Europe it's the same place on the opposite side however if your fuel tank is metal its inside the tank and it your vin is 38, 39, 64, or 68. it's also inside the fuel tank.
