<<SNIP>>Probably not. Here's why. The fuel return line is to
avoid/prevent vapor lock.<<SNIP>>

  
An alternative view:  The return line is there to help prevent the fuel
pressure from overcoming the wimpy float/fuel valve combo in the Carter.
I currently run a pressure regulator as well as the return line, but I'd
be willing to bet that you'd be just fine with a regulator.

Andy,
Probably not. Here's why. The fuel return line is to avoid/prevent vapor
lock. This occurs within the fuel pump primarily. If you release the
vaporized gas (which occurs becaues of the vapor lock) into the fuel
return line, there is no back pressure that it has to overcome. So the
vapor can easily escape. But in releasing it into the main line, there
is all that gas there which does provide a back pressure obstructing the
vapor release.
