LS9 fuel rails, stock feed as return, and 6AN PTFE line as a feed now.
Running E85, and dual walbros, no issues so far, and FPR is before the rail

So you run the feed to the reg block off one port and then out to the rails and stock feed as a return? I’m not sure how the ls9 rails are set up. Is it a single feed to the rails like the trucks? Also I’ll be boost reference if that means anything I don’t know if that’s how superchargers are

kaze_v8

No, my feed comes in on the right, then on the left it goes into the fuel rails. The LS9 rails are like truck rails.
Then my return comes out the bottom of the FPR. So nothing is blocked off in other words

And yeah its boost referenced, thats what that small nipple is for on top of the FPR

Got ya. And no issues with idle or starting it up? I don’t see anything hooked up to reference the boost but you must not need it with a supercharger I assume?

kaze_v8

No issues at all.
I didnt have the boost line tied in on this pic, but yes i do need it with a supercharger

Nice you get any dyno number yet? How much boost you run? Also I got some fast fuel rails for free and want to run those on my nnbs intake. I know I have to make brackets to hold them down but should I use taller ls1 style injectors with adapters or would teuck sytle work on these rails? I know they have a slight slant to them towards the firewall so I was told ls1 taller injectors work better cause of that. Anyone have experience running these fuel rails not on a fast intake? I have my stock teuck rails so I wonder if I set it up like kraze8 has them if they would work with the regulator set up? Thanks

No dyno numbers since im AWD, and im on about 12lbs of boost.
Cant help you on the fuel rails, i have no experience with those
