[Vwdiesel] RD28 help now

[LBaird119 at aol.com]

  YAY!!! I was told today that the engines arrived yesterday!
Of course I had to run right down and look at them.  PURDY!
Non turbo though.  :-P  Looks pretty easy to adapt to the 
manifold outlet and go though.  :-)  Even has an oil return.  
This leads to one oddity that I need help identifying. 

  On the back of the alternator is a pump of some sort with 
a return line to the pan and a banjo bolt connection to the 
side of the block.  There's one cut off hose and a small, vacuum 
sized hose as well.

  Pan is VERY shallow so fit should be very easy.  One came with a 
clutch fan and lower flywheel cover.  The other, no fan but the behind 
the flex plate actually, plate.  Both came with starter, alt, PS pump, 
A/C bracket I presume, IP of course.  There's a throttle position sensor 
but nothing else seems to be electric except maybe a fast idle solenoid 
and the stop solenoid.  :-)  They even have a cruise control diaphragm 
on them.

  If anybody can identify that pump and or find me a book that covers 
that engine (regardless of car) that'd be great. Of course I'm not likely 
to find anything in the US for it.  I can't hardly find anything about it on 
the internet!

  So to y'all overseas members (maybe Canadians too?)  HELP!!!  :-)
