One point I think about, see your question 2)
2) Is the fuel constantly returned from the carb needle inlet back to the tank, so the carb takes whatever amount of fuel the Venturi sucks? If so, how to keep the 0.25 psi within that line?
When it is possible to create a (nearly constant) atmospheric fuelpressure near the carb by using a return line I think the 0,25 PSI isn't so important anymore, that's why I would try two returnlines to the fueltank, see post 13.
So maybe you can easy and automatic create one undisturbed air connection between carb and tank, the second line is used by the fuel to find a way back to the tank. Interesting to try out!!!!
Success,
