Like has been mentioned, most will get away with smaller 3/8 line and never know there is a fuel delivery problem on the street, as most here don't bother or even worry about track performance, but will quickly find out there is ET and MPH to be found in that area as soon as they hit the track.

In nearly every scenario when I've been involved with a decent running street car, they've benefitted from 1/2" line and a good pump feeding it. Surprising the amount of people that spend a bunch of money on engines, worry about the HP they make, then skimp on the fuel delivery system. We've all done that, myself included. I quickly found decades ago as power level keeps increasing the fuel delivery becomes a key player. These days right off the bat I just spend the money and shoot for an in tank pump and 1/2" lines and call it done so I never have to revisit it again as the car evolves further.
