I recently bought a fuel setup from rx7store and im at the point where i have the rats nest out, im not sure on what i should do next, and im not sure how the secondary fuel rail comes out.

It's got two bolts that hold it down to the lower intake manifold. Make sure you open the fuel cap to releave the pressure on the system or your going to get a lot of gas all over the place. Some is going to spill out anyway so do keep a rag handy. Other than that just look for the bolts there are only two on each rail.

i took the 2 bolts out, it seems to be hung up on something, :(

unclip the injectors...

and there are fuel hoses attached to the fpr and opposite end...
