Carb fuel line layout differences?

[757CafeRacer]

So I have a 76 Honda cb750 ss. was wondering if the layout of the fuel lines would matter or not. The 2nd picture has two fuel filters. Is there a better setup? or does it matter

I would tend to keep every carb have his own fuel supply.
My RD has 2 separate petcock links each for one cylinder.
Important is that no fuel is restricted into the bowls and to fill these 4 bowls you need alot of fuel.
Filter are good but again be careful that they are big enough, i once had an issue with my KZ when the filter didnt supply enough fuel to the carb.

I also have a 76 super sport and I use the tee like you have in the first photo with one filter. Except mine comes in from the bottom. Zero problems.

Yeah Son!
