Hello Thomas, I would not advise attempting to replace the entire tap, mainly because it is made from brass, so corrosion is not a problem, and it may well up end up taking till Christmas to do... :lol: The only part which degrades is the rubber 'O' ring. To remove this item you will need two small imperial spanners so as to loosen the control cable. Then to release the actual arm from the tap a small screwdriver is required. Classicus offered some excellent advise in using clean white rags to sit beneath the tap just in case any item should fall. Fit a new fuel resistant 'O' ring of the same dimensions and then refit. You will need a good light source and lots of patience and be prepared for an aching back and sore fingers, but just make sure that no women or children can hear when you start describing the tap and the Rover using very colourful language... :lol: Ron.
