Hi all quick question , my 2010 diesel outback has developed a leak from passenger side rear . According to mechanic it is coming from a secondary filter ?? He said it has never been serviced so it is failing,  Ive never heard of a car having 2 fuel filters , if it is leaking can anyone point me in the direction of the part number so i could get hold a one to replace it. 

Many thanks !!

Maybe the dpf (diesel particulate filter)? Not sure, wiser heads should chime in shortly.

It could be a diesel pre-filter as some manufacturers fit them around the fuel tank area, the pre filter is usually there as a water separater to trap any moisture in the fuel before it gets up to the main fuel filter at the engine, however having no experience with the boxer diesel thats just a guess as to what it could be 👍
