It's unlikely the high pressure, that's a pipe from the steering hose that only turns into a hose somewhere behind the engine. If that one even leaks a little you'll lose all power steering within an hour, it's like 200psi.
There's two low pressure hoses, one comes back from the steering rack and into the reservoir, unlikely leak. The other one goes from the reservoir back into the pump and is all rubber, that's probably the culprit. I don't know what the name is... it's the "really squiggly one".
