So my dad decided to start selling nitrous kits for snowmobiles and atv's as well as get a fill station

. The fill station was around a grand for the pump and a digi scale.
For those who are wondering hard cost on nitrous is $116 to fill a 65 lb bottle + $7.50 to rent the bottle. Granted this will vary from area to area, these prices are in Idaho. I can't wait, at $2 a pound I might spray a little more often
