Im in the middle of the install for my NX GenX II kit, the main nitrous line(from bottle to engine bay) has a gold AN fitting and a blue AN fitting on opposite ends. Which end goes on the bottle and which goes onto the solenoid? It seems they both fit either way, and im not even sure if it does matter but i want to be sure.

Thanks!

 

Shouldnt really matter either way.

Now I'm guessing here, but the gold could be a cadium or zinc plated steel fitting and the blue should be a anodized alum fitting. When installing, keep the steel on steel and the alum on alum. Now, if the gold fitting is just and anodized alum fitting like the blue, then of course it doesnt matter one bit which end is which, unless of course they are different sizes - but I doubt that's the case.
