Just a fyi, 'Tubing' is measured OD, 'pipe' is measured ID.
I couldn't agree with the raceman more. I've ran 'through' the 330 cone with the fuel pumps off since the burnout (because i am stupid) with a Dominator and their large fuel bowls (with a 800HP motor), and had a lesser motor with a pair of 4150's made it to the 1/8th mile before any sign of 'sumptins wrong'. Typical high HP car will burn about 3/4 to 1 gallon of fuel on a full 1/4 mile pass (driving the lanes and return) . Large float bowls will get you a long ways down track. But the carb will deliver a funky A/F as the fuel level in the bowls drops. Patrick James at Prosystems will beat you up pretty good if you tell him you set the float level to the bottom of the sight hole. He puts those clear windows in his upper end carbs and says it will only deliver A/F properly if you set fuel level to mid-window. If your fuel pump can't keep the level there,, you need a better fuel system. Why that level and not the bottom of the hole I don't know,, it's just the way the carb guru wants it done. How do you check that at 140+ I'm not really sure (LOL)
Back to 'overkill on the fuel system isn't such a bad thing,, just expensive!
