Euronatura, I would leave things alone unless there is a problem. You might dislodge some dirt etc. I'm just thinking of draining the tank from the bottom, to actually clean it means taking the tank out of the car.
I just read your thread about your buzzing fuel pump, did you put a new one in and if so did you notice any difference?
