I'm about to do a fuel system on my car for e85 I think I know how I want to do it but would like to see a few other options before i commit. This is what I have in mind for mine

that would work or could go a lil simpler and run all -8 to the back of one rail. Thin cross over in the front with -8 and come out the back of the other rail to the regulator. That way u can save cost on fittings and don't need a Y. U can block off one port of the regulator since it want be needed. But both ways will work. Its up to u.

I would keep it -8 all the way for the feed, and just -6 for return only. Remember E85 takes like 30% more fuel than 93. So the bigger lines will help.

Will work fine how you have it drawn.

I have seen where big turbo cars will feed each rail independently from a Y block, then have 180 fittings with smaller line so it tucks against the injector rail and then to the regulator. I am undecided as well.

I run a dead head on the stock returnless rails. Goes from tank, to regulator, to stock rail fitting.
