<VV> Early Spyder fuel return

[Andy Clark]

Rusty, I removed the fuel return line from the 180hp Cord after installing
an electric fuel pump and pressure regulator set to 3 psi. I could see no
need for the return line with this configuration, and after running this way
for over a year have had no issues.
For those more knowledgeable about stock Corvair fuel systems on turbo
motors, I have a couple of questions:
How does the fuel return port on the side of the filter regulate fuel
pressure accurately. It seems to be just a fixed orifice. Is the fuel
flow/pressure from the stock mechanical pump so high that it overcomes the
inlet seat in the YH carb, and that's the reason for the return line?

If I have a fuel pressure regulator installed on an early Spyder, should I
still run a fuel return line?

Any input would be greatly appreciated.
