how can I tell if my power steering pump relief valve is malfunctioning?

What is your question?

my 96 f-250 w/ 7.3l powerstroke, blew the high pressure line coming from the pump, after replacing it, I was trying to bleed the system, turned the wheels all the way to the right, no problem, then when I tried to turn them to the left, the steering got hard, and I got out to see a puddle building under my truck. not the same hose, and as soon as it stops dripping, I'll find out just where the new leak is. Should I be looking at the pump for possible rebuild? Or is it possible that the relief valve just needs replacing?
