Picked up a used NX single nozzle kit with the lightning solenoids, and had a quick question. I was going to mock up the system tonight and noticed that my fuel feed line is alot larger than the feed from the noid to the nozzle. It also has larger fittings than what my schrader valve has, one end is a 90 and the other is a straight. Anybody got any ideas as to wether this is how they come nowadays, do I need some kind of adapter, or just switch the whole line out for a smaller one? I used to have an old NX kit and dont remember having to buy any adapters for the fuel rail, but that was about 10yrs ago, so things couldve changed lol! Thanks in advance...

Hmmm well I have a older NX single nozzle kit, and the fuel and nitrous line appear to be very similar in diameter and length. Did you but this kit new from NX?

No, I got it used. The lines from the solenoids to the nozzle are of equal length and diameter, but the feed line from fuel rail to solenoind is larger than the others, and is WAY larger than the rail threads, it also has a built in 90dg on one end..

Okay, well i've really never paid attention to the size of the feed line actually. Now you have me curious lol

4an from fuel rail to solenoid and 3an from solenoids to nozzle.
I have threads everywhere with all kind of pictures ...check em out see if they look the same.

I did change the ends on a few of the lines

I have a nx kit on mine, I didn't need anything special for the fuel line. It was the right size for the fuel rail.

Do you have an adapter on your rail? Looks like a black fitting screwed onto your rail. Also my fuel line is about 18-20" long where on your setup it looks to be maybe 6" from rail to solenoid??

yes i have an adapter on my fuel rail. The fuel line going from the rail to the solenoid is shorter but i had that made when i had the kit on my old setup. I just didnt like all the excess line. That shouldnt matter in length size.
I also shorten my nitrous line going from the solenoid to the nozzle which i shouldnt have done. Those need to be the same length or close to it.

It sounds like you may have a -6 fuel feed line which would be a lot larger than the test port on your fuel rail. If you would check what size wrench fits the nut on the line you have that will tell me what size your line is.
