Spent several hours today driving around town looking for suitable PS 12mm return hose. No shops had it including NAPA. Didn't try the dealer because I already know what list price/meter is!
I did buy 2ft of 11.9mm PCV J30R7 hose. It has almost same overall dimensions as original, but has low working pressure rating (2.4bar; 35psig), burst 175psig. Don't know what pressure there is in return line. Probably not much, so perhaps it might work on temporary basis?
The SAE spec for power steering return lines is J189. This is what it says:

This SAE Standard covers hose fabricated from fabric braid and synthetic rubber, assembled with end fittings or user applied clamps for use in automotive power steering applications as flexible connections within the temperature range of -40 °C to +120 °C (-40 °F to 250 °F) average and 135 °C (275 °F) maximum peaks. Hose assemblies shall be suitable for 1.72 MPa (250 psi) maximum working pressure with end fittings and 0.69 MPa (100 psi) maximum working pressure with user applied clamps.

SAE 100R6 is probably overkill (400psi rating) but may be easier to find?
I guess I need to keep looking!
