pentosin leak in power steering hose on 1990 Coupe Q

[schulz@tif623.ed.ray.com (Peter Schulz)]

I would like to replace the hose from my hydraulic (pentosin) 
resevoir to the pump on my 1990 Coupe Q.  The hose (pipe) has 
ridges (cooling fins?) running through the mid-section.

I looked at my microfiche, and it appears that the ridges are
for cooling, but there was also an alternate part depicted, 
without the ridges, but no description.

Can anyone recommend a non-dealer source, or should I just give
Linda a call???


TIA!
