V6 fuel rail

Hi guys.

im new to v engines.

Im trying to get away with using my factory fuel rails.

the standard application uses a regulator in the tank to dead head rail no return.

the rails are connected by an 8mm od pipe/tube.

my thoughts are running parallel using the original inlet as the outlet to reg to return.

I’m thinking with decent size feed line this should work but if the original inlet now to be outlet acts as a restriction will the injectors maybe see more pressure than the reg?

my power goal from this is 550whp 10psi e85

thanks

Hello yes that will work perfectly
