I bought a fuel rail/intake manifold/throttle body combo and the fuel pressure regulator didn't come with any mounting hard ware however I know it is a bolt on. Is it possible to run this with just going down to the hardware store to get the proper mounting bolts or am i screwed?

here is a sample of the the fuel rail and regulator.

 

You need to reword your question. Are you asking can you drive the car without the regulator on? I apologize if I missing something. As for the mounts bolts I believe those are 10mm which you can find anywhere and if you have a civic already then take yours off and use those because that's how the AEM kit comes. I too have that same setup.
