LS3 swap problems
Ive almost got my new 650hp LS3 ready to go in the car. I do not understand the fuel adapters for the FAST 102 intake. Has any one who has done this help me out? I know I need some adaptors But not sure what.

ID850 Injector dynamics for ls3. FAST fuel rail. Injectors fit perfect no spacers or anything. But the adaptors seem to be all wrong. I cant seem to find another set-up on a CTS-v to copy.

Oh, I thought you were talking about the spacer setup!
Huh.... if you are using the LS6 wiring harness, I believe you need a USCAR to EV1 PnP adapter ... but you've probably got the LS3 harness... so I would have thought it was plug and play. What car did you pull the harness from? It has LS3 style injector connections?
I don't have this setup, just trying to help out.

Post pics of what you have. I didn't need any electrical adapters when I installed my ID1000's on an LS3 fuel rail, LS3 fast102 and stock LS2 wiring harness. I did have to use the injector spacers and spacers under the fuel rail bolts. The injectors looked like they fit fine but blew fuel all over so I had to take up the extra slack between the rail-injector-intake.
