I have a complete 99 EX motor I want to put into my crx hf. Can I use the fuel rail off the 99 motor or use mine? How would I hook this part up?

My crx is a 91.

 

hmm, if i remember right you can use your stock fuel supply line but you will have to extend your return line because the fuel pressure regulator on the y8 is on the pass side whereas the crx fpr is on the driver side

 

could i just use the crx si fuel rail from my si intake manifold? That would work wouldn't it?

 

The EX rail is nicer just use it and your lines. I did the same swap in my old rex.
