<VV> Question about Turbo fuel return

Frank, et al,

If gotten a range of strong recommendations, including install the return
line and reduce fuel pressure (install pressure regulator) to avoid carb
over-filling.  Seems to me that controlling the fuel pressure is the least
challenging solution. 

I have one remaining question:  if electronic fuel pumps are available that
run 1.5 - 4.0 PSI, then why is a pressure regulator necessary?  

Thanks for your thoughts.

The 63 return system does not change any stock parts, either the filler neck
or tank.

It uses a rubber "T" in the vent line between the filler neck and tank,
replacing the typical straight piece of rubber hose on non turbo models.

This "T" has proven troublesome, depending on which supplier, so if the
filer neck is out, solder a nipple on it so you can just run the return line
directly to it just like late model (68,69) cars do.

Yes, the return line should work better. But, I know people have
disconnected the return line to drive when the rubber "T" failed so they
could get home. ANd since you have everything removed from the car, adding
the steel line and rubber parts should be easy.

I do not know the filter question answer.
