well servicing my 55 seems to be better in theory than in practice!? I decided to try and change the fuel filter to try and correct some judder. After following the fuel lines back from the tank I finally found the little swine under a protective cover covered in rust and looking like it hasnt been changed since the car was built!? Since its a sunday the only place I could get a filter was halfords, I took back the part they said would fit and it doesnt - imagine my surprise. Does anyone know what the part number is and where I can get one from? There are several different types on ebay, I dont know which one is correct!? HELP!
