Thank you for taking the time to look closely at the photos.

The hose you are referring to is the fuel return which is connected to the
fuel pressure regulator at the end of the fuel rail.  In this case there is
a short piece of Aeroquip 601 hose between the visible fitting and the
regulator.  The hose is protected from fraying by a machined fitting and the
clamp is stainless steel.  This is only place on the engine where this
method of attachment is used.

Your post did encourage me to look at some other hose connection points on
the engine.  I have oil and cooling lines to the turbocharger.  They are all
steel fittings - but one....  a -4 oil line to the turbo.  That one
definitely will be changed!!!
