Mr
i have a problem with my Mercedes C350 fuel gauge, I had changed the petrol pump then after 2days I've changed it my fuel gauge just dropped to empty but the orange light never came on then I refill at the petrol station the gauge still never went up. I now have the tank open wanna see or know the problem and I'm stuck. Please help




I'd say if your fuel level worked on the old pump and since you put the new pump in it now it doesn't work, . I would say that the problem is in the new fuel pump as that is where the float is.
Since you have the tank open, put the old pump back in plug it in, turn the ignition to the second Notch and see if it registerd fuel. If it does you have your answer. I'm guessing you didn't buy a genuine Mercedes fuel pump?
