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.
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.
Jim
