Are the ends on nitrous lines always the same color. Like are red always fuel and blue always nitrous? That the way it is on the NX kit right? So if I can find a blue NOS line would it be nitrous or fuel? The whole reason I ask is because I can find NOS stuff here but that's about it.

Thanks,

 

Color usually is red - fuel blue - nitrous (think about it, fuel, fire, hot, red... nitrous, cold, blue)


It doesn't matter which one goes for what though.

Same line/ends, different paint.

 

Some other guys on this page told me they were different. Said you can't use a fuel line for nitrous. So are both nitrous and fuel lines the same or what?

 

A nitrous line will have a teflon interior (white if you look inside the line). A fuel line may be teflon, or may be rubber (black interior). Some rubber lines will let a bit of fuel through them, and leave your engine bay smelling like fuel, so your best bet is probably to use teflon everywhere.

What color the ends are doesn't matter, and I wouldn't just assume that the color will tell you what kind of line it is.
