How do go about installing fuel system?

I think i got this figured out.... Out of the sending unit Ill run a short peice to the canister filter, then link that to the fuel pump. From the fuel pump up to the holley filter then to the regulator then run both lines out of the regulator into my Y block. Then 1 line running from the Y block up to my fuel log that feeds both carbs. Does that sound about right? All lines and fittings are 3/8 NPT. But would i need a larger line out of the Y block to the fuel log?
