wel,, i see it this way..
you are running a carby... which as a float bowl... so there is always a reserve of fuel there.
the 6psi is needed to overcome the float needle pressure and flow fuel into the float bowl.
as long as you have 6psi at the float needle, it doesn't matter what pressure drop you have...
see, the difference between EFI and carby is that the fuel is static, except for what is being used.. whereas EFI, the return line is full bore, minus the fuel being used, and the feed line is always runnign at pump maximum capability...
carby is not like that, as you have a dead head to the float chamber...
so I reckon... it will be fine.... to test the theory, you just need run a line to one of the carbs  and push the float down to get the expected maximum flow, and see if you maintain pressure..
i doubt a single 8mm fuel line will have a big pressure drop for the fuel velocity you are using...
i reckon just do it.. if you have a pressure drop it will only be 1 or 2psi, and so you can just bump up the regulator a couple of psi
too easy 
do it the easy way first
