New to NO2... need some help.

[Agent_4573]

I just bought a zex 75 horsepower NO2 kit and had some questions about it. I'm really in the dark having never used nitrous before. For a 75 shot, am i gonna need a new fpr or fuel pump? What else do I need and what else SHOULD i get for it? pressure gauges, purge valve, what? And what is up with the purge valve, do you need one and when do you use it? Also, if i'm only going to use it once in a while, do i need a bottle heater, or at least a blanket? Any tips from NO2 users would be greatly appreciated because i really don't wanna go blow up my car or break the no2 before i can really get to use it. Thanks guys.
