thanks, I could probably do that but re-using it is manily just for convinience and one less thing to do since it is already done. putting in a bigger line might be easier then trying to fit a fuel cell in the engine bay, If I have to put a bigger one in there, should I be safe and go as big as 1/2"? bigger? I am not sure how much nitrous I am going to need later on, it may be as much as 800hp when I am done.
