Which power steering hose is this?

So I have a power steering leak in the hose in the picture below. The leak is at the metal elbow in the hose on the passenger side. So which hose is this the return hose or the pressure hose? I haven't had any luck figuring out which one is which and would like to order the right part. Additionally, does anyone have advice and things to look out for when I replace this? Any additional parts to replace besides the hose?

On the surface it looks like the hardest part will be getting the skid plates off and back on.
Thanks in advance

 

the one with the arrow is return, the other is supply. The return hose has the pressure where as the supply won't have pressure til it exits the power steering pump

 

So it sounds like I need the return hose. Any chance anyone knows a part number for the return hose? my leak is at the first 90* elbow in return line closest to the reservoir if that helps.
