Power Steering return hose leaking on my 09 328i BMW

Hi guys. So I just found out that the power steering return hose on my car is leaking. Number 7 on this diagram. http://www.realoem.com/bmw/enUS/showparts?id=PH53-USA-11-2008-E90N-BMW-328i&diagId=32_1569

I was quoted $333 for repairs including parts and labor but I don't have that on me at the moment so I was thinking I might do the change myself.

Found the hose for about $60 here which seems to be a pretty good price.

I was wondering if this was something relatively easy to do? Or would I be better off taking to a mechanic when I can.

Thanks!
