I use a non adjustable bypass regulator from Kinsler for my Webers with a return line. It was preset to 3 psi, nothing to adjust. I do disagree(if I understand the conversation correctly) with the flexibility of the mounting location. A bypass regulator must go after the carbs with a return line to regulate the pressure before the regulator and a regular regulator must go before the carbs with a dead head setup to regulate the pressure after the regulator.
