Dual Carb with fuel return line Options

[ndfrigi]

Hello Teeners! Is there anyone can share any pictures how they do a return fuel line especially on the carb side?
Since I will be replacing my fuel lines to SS and removing my fuel tank to clean, much as well prep everything with return line.

I have Weber 36 Idf with 32vent

Thank you!

The Webers (and Dells) do not offer an in/out port. Therefore, it will be "teed" outside the carbs.

I was also curious about what Mark offered: where did you find a pressure regulator that will knock the stock EFI pump down to 3-4 psi? I'd suggest much more system pressure than that and you risking over-riding the float/needle valve.

I run single-line on the race car with Dells.

I'm running this Malpassi bypass regulator. So far it has worked perfectly holding the pressure at the carb at a steady 3.5 psi. It has been so steady, that I finally pulled the pressure gauge after monitoring pressure for 3K miles without seeing any variation in pressure at all. I'm running SS lines.

The important key is using a bypass regulator that bleeds off enough volume of fuel from the supply to maintain pressure rather than choke down pressure like in a typical dead end regulator. I almost went the PMO route because it is supposed to do the same thing, but now glad I didn't after reading Mark's post.

Are you using the "boost reference" port or just plug it and it works as just a regulator with a bypass?
