Is there a good source in the US for the orifice? Haven't been able to find one on the "normal" aviation websites.

If you want to make your own...

Take a set screw that you can thread into your fitting of choice.
Drill a 1/8"(3mm) hole down the middle of it.
Fill the hole back up with solder and then drill a #60(1mm) hole through the solder.

It is easier to drill the larger hole through the steel of the bolt and then drill the #60 hole through the softer solder.
Solder machines even nicer than Brass.

The hole does not need to be ultra small if the path through the solder is 4-6mm long.
A 1mm hole is 10x easier than trying to drill a 0.4mm hole.
The longer path makes up for the larger hole and is also less likely to ever get clogged.

What fitting is everyone using to mate with this jet?

I see the threads on the jet are M5x0.8. I assume I can find the correct fitting, tap it with a M5x0.8 tap, then screw it in with fuel safe thread locker.

Thanks for the assistance.
