I was scratching my head on where to get the fittings for the primer system on my new XP 360 Plus.  So I just called

Superior and asked them.  Fred there got me the parts I  needed.  This type tubing/fittings are supposedly newly

designed Lycoming stuff.  I had a choice of a 21 or 28" line so I got the 28" since I would be adding one coil down

low near the engine.  The brass fitting was 1/8" NPT for my primer solenoid.

This the the PN for the 28" line.

and the PN for the fitting.
