When I rebuilt my pump, the pump was good but the can leaked. I purchased a gasket rebuild kit through the local Napa Auto Parts store. I requested a genuine Ford kit and they came through for me. It was about $15.00 (sorry, don't remember the part #) Easy to rebuild, just take note as you pull it apart what gasket and O-Ring goes where. Great time to knock out any dents that might be in the reservoir can. Make sure you do it in a clean environment as to keep dirt out of the pump. Remember, no matter how much you drain that pump, when you crack open the reservoir tank from the pump body it will make a big mess. Do it over a drain pan. Good luck. Mike
