What size is everyone using? The inlet to the redrive is 1/8" NPT and the
exits are two 1/4" NPT.

Perry,
  I think the AN-4 fitting could be somewhat restrictive to return
oil flow to the pan......IMHO

That engine mount hole in the center housing is 12mm x 1.5mm thread.

http://www.anplumbing.com/shop/index.php?shop=&dept=Aluminum

part #9919BFG is a 12-1.5 metric to AN4 aluminum adaptor.
How about just drilling through the iron and installing one of 
these? No tapping required.

Paul-
If you’re looking for a new home for your PSRU oil drain; I found it 
was really easy to drill through one of the engine mount holes on 
the plugs side for my oil return.  The existing stud hole sizes are 
just shy of the ¼ NPT we need and the holes are above the oil level. 
 I put my return into the bottom-rear hole (see picture). 
 
This of course assumes you aren’t using the engine mount area for 
something strange…like your engine mount ;-)

Hi, Rusty....My 13b has an aluminum plate covering the old injection 
pump location. Do I just drill and tap for an NPT fitting in the 
plate covering the old pump? 
 
Ooops, I just remembered that I'm actually returning to the turbo 
oil drain location on the front cover, and not the injector pump 
location.  When I took the turbo off, I just made an aluminum cover 
plate with a hole tapped for 1/4" NPT.   
 
 You don't by chance have an old picture lying around that shows 
your plate and/or fitting going into the engine do you? 
 
Amazingly, I don't have a picture that shows it.      
 
 My return line presently goes to the oil pan, but to drain the oil, 
I have to first remove the PSRU drain line. It would be better to 
run it to the oil oil injection location.  Thanks for the info.  
Paul Conner 
 
I ran my oil drain to the oil pan plug location on the original 
engine.  This violates the rule of returning oil below the level of 
oil in the pan, but it worked fine.  Having to remove the PSRU drain 
line to drain the oil was the best part of that system.  I left the 
line free, so I could remove it at the redrive, then lower it toward 
my catch pan to drain the oil.  It was totally mess-free.  I miss 
that now, especially when I have to drain a little oil to make up 
for the pre-mix scavenging.
