There is really no way, shy of installing an electric valve in the line between the pump and the regulator, to shut off a mechanical pump, and I don't know if that would be feasible.
I built mine originally as a Factory Five Challenge Car, so it I was already set up for fuel injection and it had the in 70 pound electric in-tank pump. I used a fuel inertia switch for safety and just wired the pump to the ignition. When i quit racing the car and went with a 392, 4 barrel setup, I installed a bypass regulator that got my pressure down to a solid 7 pounds, then added a Holley 1-4 pound regulator at the first carb for the Webers.
Sounds like the fuel leaking back into the carbs may be part of the Webers though. I may start another thread about what guys do to stop it.
Again, thanks for the replies, very helpful.
