Hello All

I have a 2.5CRD diesel. 2002 model. Can anyone tell me how to fuel level sender unit as I can no longer read the fuel level accurately? Unlike the gasoline model, I think that in the diesel, the sender is part of the anti-rollover valve in the tank.

Do I need to replace the whole tank?
Or can I just replace the sender unit and presumably the associated anti-rollover valve?

Many thanks in advance, kkc.
