I am installing a zex direct port system shortly on my car. I have lonnies billet rails. I am wondering how to hook up fuel supply to nitrous since kit normally just puts fitting where shrader valve is on factory setup.

I do have a boost referenced regulator setup .So do I have to get some fitting to t into the main fuel line feed to the drivers side rail or can I take my fuel off the fuel regulator?

 

You could take the fuel straight off the regulator as long as it's a outlet port.
