Vacume for all aplications should be taken from at/in or near throttle body to reduce pulsing affect.  David RV6A Rotary.

Jet not important unless you spend a lot of time idling at stop lights :>)  It is an emissions control thing. The small pocket in the port that is 'curtained' by that jet should be smoothed out and eliminated using a die grinder for an aircraft installation.  At least that is what I did with mine FWIW.

 I just read an article on the Renesis and the following comment was found:

"A small tube within the intake manifold provides a small, high-speed air
curtain, which enhances fuel atomization."

This is the first I have heard of this use of that tube.  I have a hose
connected to that tube which I am using to provide vacuum to my fuel
pressure regulator.

Should this tube be left open to provide that "air curtain".?
