I would buy a new twin cylinder nitrous express kit. Most a your questions are answered in the previous replies. If you want to try a different installation location, other than what has already been mentioned, then that is up to you.
You are getting the same anwsers in open forum as you did in my pms. Nitrous Express has a fuel soleniod for methanol. They have a excellent power sports tech line for assistance.
I have been using nitrous on my banshee since 2006. Current top end has been together since 2008. Spend the money and do it right the first time.
It will be much cheaper than melting it down, with a questionable set up. Just my opinion, which isnt much.
Good luck with whichever way you chose to go
