Need technical input on Fuel System Setup.

[GroundPerformance]

I'm deciding on what fuel system configuration to run on my S13 KA24DET setup. I need it to be basic setup and good enough to support E85 and around 600whp. Below is what I have in mind at the moment and just need to know some PROs and CONs in comparison to other Dual pump configurations either Inline, Y-Fitting and others. Nothing is set in stone at the moment but unless I see major issues with this configuration I will be proceeding as planned.

To make this work on S13 I will add and extra fuel port the stock fuel assembly for the fuel return. I plan on using all the stock fuel hardlines currently on the chassis. From the hardlines to dual 6an hoses/fitting feeding the rail on both ends.

Stock Fuel Hard Lines;
Before >>>> After
Fuel Feed Line >>>>>>>>>>>>>>>>>>>>>>>>>>>>> Fuel Feed Line 1
Fuel Return Line >>>>>>>>>>>>>>>>>>>>>>>>>>>> Fuel Feed Line 2
Fuel Charcoal Canister Line >>>>>>>>>>>>>>>>>>>> Fuel Return Line
