Best fuel pump for Webered Six-cylinder, and does it need a return feed? Options

[Qarl]

Working out the plumbing details for my six conversion for the fuel lines. I've read a few threads and I'm still confused.

I'd like to keep the fuel pump in the front underneath the tank. (The 1975 car I'm staring with had it there to begin with.)

What sort of pump should I use to get the 3.5 to 4.5 lbs pressure I need for the Weber 46s? Hardi, Bosch, Rotary, Holley?

Do I need a return flow line?

If I have a pump that flows at 3.5 lbs, do I need a pressure regulator.

I also plan on installing a filter before the pump and one before each carb.

Thanks,

Karl

A fuel return line is not required for carbs.

correct, but search around a bit. I seem to recall that some people choose to use a return line for reasons beyond my understanding.
