Cant help you there sadly. Think you can access it from the boot though. Under the carpet should be a round hatch which unscrews

cheers anyway,  anyone done this? how hard for a novice?

As Rhyso says it's likely to be the sender which is attached to the bottom of the fuel pump. You can access the pump which is under the rear seats. I'd try giving the sender a clean as a first step, just make sure you haven't got a full tank of fuel before hand.

thanks dom, tank is half full, is this an easy job for a novice? what do you clean it with?
