How to change the engine fuel filter on Mercedes-Benz. This is done on my E-Class W212 Diesel engine (OM651) but the procedure is mostly the same for other models.
If you like to do it the recommend way from MB you should use a plier special made for the click clamps part-nr (171589003700) but I don't had any at home and the normal plier with a flat screwdriver worked flawlessly.
And you should also order new click clamps, they should not be reused again, and should not be replaced with any other type of connector.
