This is another one I need. Same situation.

  This is the oil feed line for the 1990 1991 turbo.

  Does anybody have one they can sell?
  Does anybody know the part number?

  BTW has anybody run Mobile One in a turbo engine?
  I would think it ideal as it is good to 500 F while
  regular mineral oil starts coking around 250 F.

I have been through a number of iterations on that one.  First I flared
the stock line, which was a -5 size, and found a -5 to -4 adapter for
the rest of my system.

Most after market turbo oil inlet plate adapters fit.  Found many places
online like Jegs..  fits any size AN you want.  ..  But Those leaked
some.

Last 100 hrs I have been using a steel 45deg  1/8NPT to AN-4.  That is
the simplest, lightest, cheapest, and no leaking so far.  The oil hole
at the top of the turbo has NPT threads (on my TO4 center section)

Thanks Dave. I'll check out Jeggs. Do you use the turbo oil banjo
fitting on the block  end or do you get the high pressure
oil someplace else?

There is a metric thread fitting on the plug-front-top area of the
forward housing that I use.  It may be where the banjo fitting was, but
it is threaded as well.  M8?  Its been many years...
