Just a quick post to say thanks for the help!! Perfect guide! One thing ill say though is the pump from Halfords which has the same code as the one in that guide, is actually identical in appearance to the Ford unit and there is no need to change any pipes etc, its just a perfect swap. Its also £17. I dont know how it will weigh up to the Ford pump in the long term, it may not be quite as robust but time will tell!
Thanks again guys!
