What led you to the pump? Where is the fluid leaking from? Is it leaking from the same place as before you replaced the pump? How fast is it leaking; just an occasional drip or a fast spray? A leaking high-pressure hose is WAY more common than a leaking pump, and it can spray fluid to other places. Except for extremely rare instances, the pump will only leak from the seal right behind the pulley. Does it keep on leaking for a little while after the engine is stopped?
