im looking into gettin some nitrous for my truck what all do i need to have a nice safe kit?

the kit
bottle heater
filter
purge
fpss
window switch

should i get a fuel pressure gauge?
what exactly does a blow down tube do?

thanks for your help.

 

Blow down tube vents the nitrous and pressure out of the cabin if the bottle should over pressurize so that it doesnt blow up and destroy your car.

 

Most good kits come with a blow down tube and rupture discs. A fuel pressure gauge is nice to have but you don't have to have one. Don't forget to pick up some colder plugs if you plan on spraying 100 shot or more.

 

i would go ahead and get the gauge and,and a nos pressure gauge for optimum bottle pressure for optimal perf

 

colder plugs are not neccessary if you shot below 100? I thought they were neccessary for any level shot?
