As I read through all of this I am reminded of the mistakes/leasons I have learned about pump placement size/style of the pump, running voltage to the pump, tank placement and g-force. But I am just a dumb electrician, not a rocket doctor.
Some need to remember there is a big difference between a tank at the rear of the car way behind the regulator and carb and a tank ahead of the pump and the rest of the system.
The fuel aeration/pressure discussion is interesting, and I have to think about how some push vacuum referenced regulators and the effect that would have in the fuel bowl.
