Ernest,
Comparing to a Cherokee may not be a fair comparison.
As far as fuel flow goes, in a Cherokee, all you need is enough to keep the carb full as the engine uses fuel.
In a fuel injected engine such as the 13B you need enough for the engine plus the fuel
that is returned to the tank.
If the fuel is returned to the tank, it won't need air to replace it 8*)
Also unless aggressively leaned the rotary will burn a bit more fuel for the power delivered so that will also increase fuel flow requirements a little.
I and I believe Larry are both using what the plans call for a -4 90 deg bulkhead fitting and have not had any problems.

With the aluminum tank, I'm thinking a short piece of tube would be easier to fare into the turtleback (out the top and pointed forward, Pat)

On a tagential issue, I started the process of getting checked out in our club's Cherokee 180 (about the same HP as I'd expect from a 13B). I noticed during preflight that the tank vents are miniscule. How big of a vent is necessary for a 13B's tank?
