Rookie nitrous questions ?

Agreed I’ve been reading up on safety items for nhra bracket racing and to have a gauge in the cab I will have to use special line. I’m will definitely use a pressure switch as well as a dedicated fuel pump for nitrous. Also a MSD 8680 for dash controlled timing retard. Timing , throttle activation switch etc.
I just put my fuel gauge up next to my carburetors which are popping through the hood so the fuel gauges outside..
