Ive got a plate system from nitrous outlet (kit # NO-10112-10) What size fitting is the fuel supply line? I've got to buy a few fittings to make my fuel system work. Ive got the professional products 85MM manifold and had a few issues with the fuel system leaking so I had the fittings welded to the fuel rail. So I want to add a fitting before the connection at the fuel supply line and run my fuel supply line for my noid there. What are some thoughts on this?

The fitting on the plate should be a -3, as for the noid threads into it are 1/8 npt "pipe" if it has AN- fittings already on it then probably a -4. AN fittings are based on 16ths just measure them 4/16th or 1/4 inch is a -4, 6/16th or 3/8 is -6 and so on. Hope that helps you out. Sounds like you have a good plan to start with, I have the same leaky *** rails thought really hard about taking the TIG to mine.

i had a few problems with the leaking so i just had them tig welded as i have many rails. it is a great way to insure the leaks never come back. i lost my porsche to a fuel rfail leak. so i like to make sure there are no leaks at all. but back to my original question. the fuel supply line that feeds the noid is the fitting in question. i know its bigger than the -3an fitting on the plate. so it is -4an in size? i need to but a t-fitting that is a female / male -6an/-6an with a pressure bleed off of 1/8 and buy another fitting that is 1/8 / -4an so the fuel supply line can attach. how does that sound?

Like this on from Summit then use a 1/8 npt to -4AN adapter threaded into it. That is what I did for my fuel pressure gauge.
