Power Steering Return Line '98 Concorde

I bought a 1998 Concorde on ebay for $2500, and I love the car. The only problem is, I had to drive 3 and a half hours with the wife and kids with no power steering. I had to stop and refill the reservoir 8 times on the way back. At least the fluid is changed. :p Anyway, the shop says the return line is shot on the power steering system. Doesn't look like too difficult of a job to tackle myself. Any ideas or suggestions? Should I try it?
