Fuel systems for drag cars

I can only tell you what I have done.
Fuel cell. Block one eight outlet, a ten to the filter, ten to the pump, eight to 1/2 aluminum line to the regulator. Two Eights out of the regulator to the carb on the nine second car, sixes for the eleven second car. 250gph pump on the nine, 150gph on the eleven second car. A mallory gerotor, and a Paxton vane. (I LOVE the mallory, but its REDICULOUSLY expensive now, since holley bought mallory. Holley wants to sell HOLLEY pumps)
Both probably would have been better with a return setup, but both ran fine dead-headed.
