How do I drain the fuel filter in a mercedes 350sdl (turbo diesel) ?

I think I have a problem with water in my diesel fuel. I want to drain the fuel filter because there way be water in there. Where is this under the hood?



I have this weird problem where my car sometimes shuts off completely while im at a red light (stopped). The radio stays on but the engine turns off. My idle speed is fine, and I'm almost positive its a fuel supply problem, and someone suggested to me it could be water deposits in the fuel.



I got this stuff called ISO-HEET that you put into your tank before a fill up, it is supposed to break up water and allow it to leave the tank. Anyone used this stuff?



Some people have told me not to use additives in mercedes but I did not see this anywhere in the manual, and it seems like if it does what it says, it would help a lot.



I also got this diesel kleen +cetane boost stuff - anyone used this?



but back to the main question, how do i drain the diesel fuel filter?

or You have to rise the idle RPM.

the other thing You have to look for is for air restricctions in the air intake manifold.



DO NOT USE ANY CLEANER, IN A DIESEL ENGINE....PERIOD

NOR STARTING FLUID. or additives.
