Hope this is not a dumb questions, but let's say I decide not to get the automatic bottle opener for my nitrous kit (nitrous express EFI stage 1 50 hp shot). And let's say i go for a long road trip (500+miles), and have the nitrous bottle opened since the start of the drive (in case I get to a stretch of freeway with no cops in site hehee ) The bottle is opened, but I will have the arming switch off. Is this ok for the nitrous bottle to be opened for, say, 1-2 hrs, since that'll be when I stop for gas, break, restroom, etc? Will nitrous leak out, or would it be harmful to the system? or should i invest in an automatic bottle opener...i rather not bec it's like $230! it's even more than the installation cost of the entire nitrous system!
