Fuel line through bulkhead fitting in shock tower?

I am using this back by the tank with the return back there. I am rethinking the second fuel line as it interferes with the air filter base. I have -8an to the bulkhead and split into 2 -6 lines to feed the EFI. I may just use one -6 line and see how it goes. If it is fuel starved, I will change to 8. Probably don't need to overbuild. Also my understanding is that with the sniper you do not need a regulator after the efi but on the more advanced EFI, my system would not work.
