Is the fuel return to the tank really necessary?

Posted July 20, 201212 yr

1970 240z, will be dropping in a built 2.8L with Z therapy SU's, wondering if I can just use an electric fuel pump with regulator to 3lbs straight to the carbs with no return line?

Thanks,

Chris

That worked for me with triple Mikes. No problems.

My SU's I ran the mech pump with the original return with no regulator - with my Mikuni's I am running a fuel pump dead headed with regulator. Never had a fuel issue either way.
