You want the specific pressure hose from Ford or equivalent. Check Rockauto.com. I remember a thread not too long ago here where a member made a braided stainless power steering hose, it should have worked fine but there was no steering assist at low speed.
The pressure switch is on that hose, but a separate part number.
There is also an O-ring you'll need for the fitting end.
The supply hose could go generic, but with all the weird bends in the hose, I would go Ford or OEM equivalent. That hose has no pressure, just a gravity drain to the pump inlet.
