 I am putting on a m20 air/oil separator on a lancair 320.  Will the Lycoming
model be best?  I have a 0-320 engine.  The only difference in the two
different models is where the return line is located.  I hope you have some
info  on this, or know someone that has done this before.
 
 Thanks in advance,
