Thanks for the help. Yes I do have two fuel pumps. The faulty one is under the back seat, if you undo the carpet it covered by a metal plate held on by 6 phillips scews. The pump itself is not making a buzzing sound like normal so it does sound like its dead. The front pump is working...

Dear all, My 2002 Td4 just broke down. The AA has diagnosed it as faulty rear fuel Pump. I am planning to change this pump myself. I am wandering how to remove the outer black ring that holds down the pump. Any help would be greatful.
