racecar fuel delivery
May I recomend this site for a quick review?

I know that some people have had problems with BG carbs, but the above information makes sense. Fuel delivery on a true strip car should come from the front, curving back to the regulator and carb with the reg as close the carb as possible.
Please give us more info in regards to your application. For example, are you running N20? What times are you presently running? Big block?
