5th Gen Module in a 1st Gen Tank

[69-er]

I've been doing lots of reading on the vaporworx 5th Gen modules but have a some questions.

I already have a factory 5th gen module and the C5 pressure regulator. If I were to keep the module's factory pressure regulator and plumb the pressure output to the Vette regulator and route the return line back to the module's reservoir would that help the venturi pumps in keeping the reservoir full? Or, is the 4th Gen pressure regulator mod available separately? I could then do away with the Vette reg.

The two venturi pumps: Along with the one pump's bottom fitting normally going to the driver's side of the 5th gen tank, I assume there is one in the module for the passenger's side of the tank. Will the module venturi pump work well enough by itself or should I also connect a remote pickup to the second pump's bottom fitting? Or maybe just leave the fitting open to suck fuel that's in the vicinity of the module? The car is an LS2, street driven.

Thanks!
