Answer
Kurt;
    If it is leaking there must be a reason why - it might just be a hose . I would look and  find the leak  before
I would go and get a new pump and all that work . and as far as the fittings on the pump you must be carefull not to strip them as they are soft wleded or crimped in place and they do break easy and the tank will also squish - bend if you forse it or pry on it.You can go to the library and look in the car tech. books - they should have the step by step inst. on replacing a pump. but I would first find the leak.   ok and the one line has a lot of presshure in it so be carefull . the other is a return line.
