Power steering return line replacement

[redmetrix]

The power steering line on my 1989 Olds Ninety-Eight has recently developed a small leak. The line itself is pretty corroded and I would like to just replace it. Has anyone on here changed this line? If so how difficult is it to do and what do I need to know when changing it? It looks like this:

Nothing special required, just drain the system, replace the line than fill up. Start the car and work the steering wheel back and forth and fill as needed.
