Power Steering issue

So I just bought an 03 manual 5 speed V6 and have put about 600 miles on it, bringing the grand total to just over 77K miles. I'm having problems with the power steering, though. It checked out when I bought it (about 10 days ago), but it's hemorrhaging power steering fluid. I took it in and got the system flushed and an additive put in, but 48 hours later it's back to steering a cargo ship...

Obviously, there is a leak or the pump or rack is out. Has anybody had any problems with '03 Power Steering Pumps, however? 77,000 miles sounds a little young to have a blown power steering system...

Thanks!!
