I've also supported 550hp with a factory mechanical and 5/16 line. Many lines now have kinks and guy dont cut them properly so the flow is much lower than it should be. That fact is, overkill sells, and in many cases, meaning a car that runs in the 12s or high 11s, they simply dont need that much pump or line. In somecases, you add so much volume in the line the milder pumps have trouble pumping against the inertia of the fuel in the line in first gear.

Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
