Carb Supply Line Size

For you guys who are running a carburetor on your track car:

What size line are you running from the Pump to the regulator (-6, -8)?
What size from Regulator to bowls? (-6, -8)

I'll be running a Pro Systems 750 ish custom carb...my first carbed fox, so I'm not too familiar. I have both -6, and -8 braided from my efi setup.

Thanks

I have a mix of -8 and -6 on mine, kind of based on what was laying around 10 years ago when I put the carb on the old car and how I adapted that to the various rebuilds and the new car.

This is feeding a HP4150-850cfm and has never had a hint of fuel starvation that I can tell.

Thanks DaveW,

I just heard back from Patrick at Pro Systems. He says use -8 from the Holley Blue pump to regulator and -6 from regulator to carb. He also added that the Holley Blue will support 525HP. I also have an HP4150 - 750 that wet flowed at 780.
