what size fuel line for nitrous setup?

Thanks for all the tips guys. I've also been reading everything I can find, and it's all starting to make a little more sense. I still have yet to find one single source of solid information about this topic, but I've been piecing it together from here and there. I'm surprised that the Mopar Performance books don't seem to go into this in more detail. I think I'm starting to get it though.

This isn't for a full race car, just a street/strip car with probably a slight emphasis on strip as opposed to any sort of creature comforts :) The car is a Mirada, so there's plenty of room to work with in that cavernous trunk!
