Power Steering Fluid Leak

[C-Notes]

At the master cylinder?

To be honest I never even noticed that there was a line from the power steering unit to the master cylinder before noticing that I had a leak. Was underneath the truck looking for it and noticed that it wasn't near the PS unit, so got up top and low and behold followed the line to the master cylinder and found the leak.

Any ideas on what to do to fix it? Replace booster? Replace hose? Replace O-rings?

Thanks in advance,
Cody
