Nitrous plumbing A1A...??..

Went waaaayyyy down the slippery slope... Ordered another crap ton of stuff...
Should have everything I need withstanding some wire and fuel hose..
The question that raised in my mind was running soft hose for the fuel side? I know not more than a foot is allowed on your normal fuel for the engine..
Still need bottle, bracket, pressure gauge, and heating blanket.. more slipping...lol..
