Hi can anyone tell me how difficult it is or can provide me with some detail as to how to replace the fuel pump drive belt and tensioner. My XJ has reached the 10 year old stage although only covered 70K and i am planning to do the timing belt and tensioner the water pump the auxiliary belt and the fuel pump belt and tensioner all at one go. I have found some good videos on replacing the timing belt but with the fuel pump belt i haven't found a video of anyone doing this apart from someone showing a video of how tight the space is between the bulk head and the fuel pump and finishing the video saying good luck :/
