Default Fuel Line Routing...Y block or T Fitting

Going from a fuel system that went in one rail, crossed over, came out the other and then to a regulator....

to a fuel system that splits before the rails, hits each one separately, and then combines at the regulator....

for cleaner look I'd like to use a "T" Fitting
are there any issues with that, or do I need a "Y Fitting

roughly 700hp out of the motor
plus a 500 dry shot of nitrous....
10an to the split
8an lines to each fuel rail,
8 an return

thanks for any advice or suggestions
