SR20DET circuit sport top feed rail frustration

[89hatchman]

So I ordered the wrong fittings to use on my fuel rail. I need something that will thread into the fuel rail and that has a barb fitting on the other side. I just want to keep this simple and run regular fuel injection line rather than the braided steel an line stuff.

What thread pitch does the circuit sport top feed fuel rail use? I have looked everywhere and I can only find that it is "-6AN fuel inlet and outlet". But that's the diameter right? Not the thread pattern?

This is getting frustrating as hell. I need to get this project together and off to the tuner before the first event.
