Default LS1 Intake and matching Fuel Rail??

Hey guys,

How do you know which intake will match which fuel rail?? I got an LS1 intake and a fuel rail and injectors seperately and it seems that they dont want to fit together. Or maybe Im missing something.

The fuel rail mounting tabs dont seem to line up quite right with the intake and it wobbles and doesnt sit flat on the intake mounts.

I did try to look for some info on this, but couldnt find anything listing for the rail. Its a returnless style and has the dampner on it.

Intake is 12560688
Fuel Rail is 12564631
Injectors are 12555894 (zoom in and you can see it there).

Thanks for any info in advance!!

Have you tightened the rail down on the intake yet?? Those all appear to be older LS1 stuff and should work fine....

I dont have any hardware yet, so I cant tighten anything down. The wobble is like half an inch between rail mounting tab and the intake, is that normal?? Whats the correct way to put these parts together....injectors in the rail then attach that to in the intake, or the injectors in the intake first??

What size of fasteners are those bolts??

Ive seen many wobble like your saying then are fine when you tigheten them down.

Personally I find it easier to put the injectors in the intake then set the rail down on them.
