Mark, Yes, a good electric pump near the tank will push fuel through a non-operating mechanical pump on the engine. That's basically what many of us do routinely when we use the electric pump to fill the carb's after the car has sat for a while. 5.5 psi at the pump should be plenty to operate the car routinely, but I don't know if it would keep up with full throttle acceleration.
