Unfortunately I don't think you're going to like my answer. The Fuel Filter in that model of Mercedes is in the fuel tank. Typically with fuel filters in the tank the only time you would replace one is if the fuel pump goes out. Our labor guide shows approximately four hours to remove the tank, blow out the lines and replace fuel filter.
