HOW MANY HORSEPOWER???

You need just over 1/2 pound of fuel per horsepower per hour.

500 horsepower X 0.6 pounds of fuel = 300 pounds of fuel

Gasoline weighs about 6 pounds per gallon

300 pounds per hour / 6 pounds in a gallon = 50 gallons of fuel per hour.

You need that 50 gallons (actually, 50 gallons is generous if the engine is properly jetted and tuned properly) at the carb; and delivered at the appropriate pressure.

If you're running a return style regulator, you need to add all the returned fuel to the 50 gallons actually burned.

First Guess: 1/2" tubing is so overly huge as to be comical for 90+ % of street-driven cars.
