Fuel Line Choice and size

Stock fuel tank, or fuel cell?
My cell came with two -8 outlets, and I used to run both into a tee before the pump. New setup is a single -10 to the pump, -8 out to the filter, -8 connector to a 1/2 aluminum fuel line (probably overkill) -8 connector to the regulator, two -6 to the carb bowls, (or two -8 when I run the crossram.)

Looking like I will be similar. 1-10 from cell to pump and 8 rest of the way. Thanks for the detailed response
