If you are going to certify the plane for IFR operation and use it as such, I
would relocate the venturi to the bottom of the air plane and use it dual
purpose and hook it up as a urnal.

That would make sense to me for a VFR only Coupe.
If youre thinking about certifying your plane for IFR using the plane for
IFR, Ive long wondered if it wouldnt be a good idea to have a single venture
running a second artificial horizon (or the turn and bank). Ive read a bunch
of articles over the years about the unreliability and failure likelihood of
the dry vacuum pumps.
Air guard squadron commander and former EOC regional director Russ Jensen
used to fly his Coupe for IFR regularly and told me it worked well.
Just a thought for discussion and lurkers.
