Does the 2009 Mercedes E320 Diesel has inline Fuel Filter? If so where is it located?
Thanks

No...in US at least, everything from 2005 forward uses just one main fuel filter.

Thanks, it helped me a lot.
I have a smelling Diesel on my car and I can see the top of the main filter wet but not know from the fuel is coming. Then before removing that hoses and filter I want to make sure that if the car have or not inline filter. My son's 2002 E 320 diesel had the same smelling and it was a leaking inline filter

A fuel filter is a filter in the fuel line that screens out dirt and rust particles from the fuel, normally made into cartridges containing a filter paper. They are found in most internal combustion engines.
Fuel filters serve a vital function in today's modern, tight-tolerance engine fuel systems. Unfiltered fuel may contain several kinds of contamination, for example paint chips and dirt that has been knocked into the tank while filling, or rust caused by moisture in a steel tank. If these substances are not removed before the fuel enters the system, they will cause rapid wear and failure of the fuel pump and injectors, due to the abrasive action of the particles on the high-precision components used in modern injection systems. Fuel filters also improve performance, as the fewer contaminants present in the fuel, the more efficiently it can be burnt.
Fuel filters need to be maintained at regular intervals. This is usually a case of simply disconnecting the filter from the fuel line and replacing it with a new one, although some specially designed filters can be cleaned and reused many times. If a filter is not replaced regularly it may become clogged with contaminants and cause a restriction in the fuel flow, causing an appreciable drop in engine performance as the engine struggles to draw enough fuel to continue running normally.
