Okay Paul, it looks like things are going ahead with the P-Port Renesis.
Would you give me the dimensions and or locations to mill the 2" holes
into my Rotor Housings? (I can't believe I'm going to drill 2, 2" holes
into the side of my engine;)I am building a high wing aircraft, I have
no idea of the head pressure from just gravity feed. (I guess I could
make a quick calculation) How much pressure  do you think the slide
throttle will require? Is there some aversion to EFI other than pumps,
fuel return lines, redundant electrical systems... The P-Port and EFI
look to me to be a great match. Two injectors on each intake tube should
provide more than enough fuel. Either way I haven't plumbed for anything
yet or made up my mind which way to go. Just working on the engine and
airframe.

Sure. Here they are. On center line of course. I split the diff
and use 8.64 inches up from the bottom.

Head pressure? Water is 65 pounds per cubic inch
so 12 inches of water is 65/144 or .45 psi. Or .0375 psi per inch.

Water weighs 8 pounds per gallon and fuel 6 pounds per gallon
so fuel pressure is 6/8 X .0375 or .028 psi per inch.

Lets say your wing tank is 3 feet or 36 inches above your Posa type carb.
.028 psi times 36  would be a fuel pressure of only 1 psi roughly.

Now if you climb out at a steep angle that pressure will be reduced
and your engine might run lean. Not a problem with a rotary as there
are no exhaust valves to burn. However you may be down on power.
I would rather use a low pressure pump and a low pressure fuel regulator
to keep things around 2.5 psi and use a smaller main jet. Similar to
the Ellison.

EFI is OK if you have some electronic technician experience IMHO.

I am not dead set against EFI but IMHO it needs to be simpler.

BTW If any electronic technicians  out there are willing to do a simple
PicAXE system, one per injector, let me know. I will help out with the
loan of HP pumps, fuel injectors, pressure regulator and PicAXE computer.
BASIC programming experience helpful. I will also help you sell
it and design it.
