Rusty,

 

You=20 were looking for a banjo fitting for the oil return line from the = cooler.  Here’s another option = to avoid the=20 engine mount.

 

Take=20 a metric-to-AN fitting, M18x1.5 to AN-10 male and cut it in half.  Drill out each half slightly = and=20 insert a piece of 5/8” 4130 and braze. =20 Very strong, easy to get on and off, and avoids the engine = mount (looks=20 close in this picture, but length of tube determines how much = you’ll miss the=20 mount).  3.5” of = tubing will work=20 well.  You’d think = it might break,=20 but if you have about =BD” of the tube brazed inside each end = (2.5” of exposed=20 tube), you’ll see this is strong and well supported from within = the engine=20 threading.  The = 5/8” 4130 I used=20 was 0.62” wall thickness, leaving the interior at =BD”, = preserving the AN-10=20 flow rate.  Took about = an hour to=20 make.
