it may not be the pump,ford use a pipe with a gland nut and olive and if it leaks at the pipe then you need to replace the whole pipe assy with the new nut,you get one chance with it,if it`s not fitted correctly then a whole new pipe assy has to be bought again,there again it may be your pump assy.If you look on Ford websites, tech`s on there say 9 times out of 10 it is the pipes at fault.
