Braided fuel lines
I was thinking of something like this

The way we do all ours, might be overkill in the beginning, but will last forever.
tank to filter/pump AN-12,
pump to Y-block AN-10,
Y-block to carb regulator AN-8,
Y-block to N2O regulator AN-6,
regulator to carbs AN-6 each bowl
If using a log or single inlet, AN-8
return line from pump to tank AN-8
air return from regulators to tank AN-6
.
For a race car with a big race pump I would use a -12 tank to pump, -10 pump to regulator, -6 regulator to carb with a -8 return line.
As far as lines I think the push lock stuff is pretty affordable, light weight and flexible.
