so i'm trying to use the ls1 fuel rail on the fast lsxr 102mm intake and they will not fit. Do i need an adapter kit or will buying new fuel rails for this intake solve this? I'm using a ls3 fuel injector. Thanks.mike c.

I may be wrong but I dont think you can use the ls1 rails on the fast intakes. You have to get the Fast fuel rail kit or something like that

and i believe you still need adapters with the ls2 rail.

You need LS2 fuel rails and 146025-KIT, this is what I ran before I bought the FAST billet rails. I sold the LS2 fuel rail but I have the 146025 setup sitting in my garage if you need it, let me know.

Or you can buy FAST Billet rails #146027-KIT.
