I just measured for you... 10mm x 1.5 looks like its a metric fitting dude, not sure if they make a -an fitting for that? almost looks like it could be tapped out to a 1/8th fitting.

Ok, I was looking through the summit catalog...

EAR-9919BFD Fitting, Adapter, AN Flare to Metric -4 AN to 10mm x 1.5, Aluminum, Blue, Each 10-31 $9.39

Maybe that one..

on my IHI VJ11 the oil feed fitting that screws into the centre section housing doubles as a restrictor, very small, maybe 1 mm orifice in the middle, your going to want to make sure you keep that, or you'll be getting too much oil to the bearings.

The thread on the other side of the restrictor seems to be 1/8 BSP, the same as the oil sender. I used a 1/8bsp female to 1/8 NPT female adapter, and some SS braided line from mcmaster.com

I used a 1/8th fitting and just threaded the fucker in there... I used like a 3 inch extension with a barbed end so that the line could clear the adapter plate and just hooked up the oil lines from there.

That trip to Lowe's was seriously over an hour's worth of trial and error. It sucked.
