That is possibly the intent on the factory design, but on the manifold,
it is just a 5/16 tube that is connected to a couple of fine tubes (1/16
inch??) that are inserted into the primaries.
It should be a vacuum source when the engine is running (which mine is
not!)  Should we try and provide this pulse of pressurized air?  Where
would we get it?
No answers yet on the chair....Mark, you are on the right track!

Bill

I thought that I heard that they provided a pulse of air (pressurized?)
during injection on the Renesis, and thus would not be a good source for
vacuum operated instruments.

Bill,

I can't comment on the Renesis vacuum ports, but as for the chairs... me
thinks you need to open the windows in your shop to vent the epoxy
fumes.

I have a few questions for the folks on the list.

While at the RWS fly-in, I talked with someone who told me that the
vacuum connection at the bottom of the Renesis stock manifold was an
inlet for a directed air stream.  The 5/16 fitting goes into two small
tubes each of which feed into the two primary ports.  Can someone
explain how this would work and if it is needed to get the horsepower
that the Renesis is capable? of?
I am considering using this port as a vacuum source for the fuel
regulator.  Is this an acceptable idea?
Could you tell me what chairs would look like if people's knees bent the
other way?

Thanks,
Bill B
