Default ls1 engine with fast intake 102 need fuel rail help

So I need help please. I have a ls1 engine with fast lsxr 102 intake and im trying to install easy bolts on fuel rail to accommodate my mods. i was looking into ls3 fuel rails. would they bolt straight up? any mods that i will need to do?

I also did racetronix fuel pump. I just drop it in that it. any mods that i had to do?

reason why i ask is because as right now i have fast fuel rails and i did not know the whole shenanigan that comes with installing this fuel rail. Something about fuel regulator? i have no knowledge on how to do this, that is why i am looking for another route.

Thank you.

fast 102s were designed for ls2 motors, so they accept stock gm ls2 rails

Any mods? like a fuel regulator? i understand the, "they bolts right up" but my question is, do i need to do any fuel line or any other medications to get them to work?

No, just spacers if using Ls1/Ev1 injectors
