Take a look, let me know. No one else I see does a T fitting in front of the rail like this, they usually feed one rail, run the crossover to feed 2nd rail and put FPR at end of second rail or they feed both rails and put a FPR between the two rails on the other side.
Any problems doing it this way? it still bleeds the pressure to keep 58psi/whatever i choose, right?

Fuel Rails
Is there any benefit to running those aftermarket rails besides higher durability and cooling effect due to using solid billet aluminum as opposed to the stock plastic rails?
This relates to the OP because I want to run a return style system as well.
I'm just trying to find the specs on stock L59 and LM7 fuel rails to see if theres a reason to change to aftermarket rails besides for the reasons I mentioned above.
Couldn't I just use those fancy 'quick disconnect to -6AN or -8AN' adapters for the factory fuel supply and return ports along with factory fuel pressure regulator? Or is factory FPR too flow restrictive at 43.5 psi rail pressure?
I have Siemens 60 #/hr injectors with dual parallel Bosch 044's, planning to run either -6 or -8 fittings and similar braided fuel hose size.

Well actually, fpr is after rails, so shouldnt affect flow to injectors as long as it maintains rail pressure.
So now I really dont understand why I cant just use stock everything (besides adapter fittings) since factory fpr are set for 43.5psi anyways. Maybe the crossover between rails is too restrictive?

my build is a swapped stang, so the motor i got didnt come with rails, regardless i plan on running e85 and making a good bit of hp, so stock rails likely wouldnt have been in the equation as i think theyre -6 size.
I'm overbuilding the fuel system so that when i grenade the motor i can step it up hehe. Can you tell i have fast rails from my picture?

Wouldn't a stock return style vortec rail system be capable of boost reference since the fpr has a vacuum ref port on it?

Also in ECU, cant you just cut fuel inj/spark signal on decel? Or maybe I'm thinking of something else.
