quadrajet plumbing question

Mike Voth · 11-01-2008, 12:55 AM

We use an Aeromotive regulator that is mounted up front, behind the passenger side headlight. Two outlet lines to a 'Y' that feeds one line to the carb. We have a return line that comes directly from the regulator back to the tank. The "Y" block has another outlet that we have a pressure gauge screwed into. 4 psi does the trick for us. If you're already familiar with the q-jet, you know that there is limited bowl volume. We have the pump pressure at it's maximum so we don't lose any volume during the launch. If we don't run maximum pressure, then the fuel in the line to the regulator stalls and actually runs the bowl dry. This might be different for an automatic. Hope this helps.
