My car has a system, but only 1 nozzle aimed at me. I need to add one under the hood, but don't know the best place to get the stuff. I found a Safecraft 54-1416 3 way nozzle and a 10 foot coil of line on Summit, but I'm thinking generic line and hardware is probably a smarter way to do it. That Safecraft nozzle looks the same as the one that points at me. Should I maybe have a 2 way pointed at me so it takes longer to suffocate as I attempt to egress an engulfed car? Change over and do 2 nozzles under the hood, one aimed at each manifold? I'm also unsure of the threads on that Safecraft nozzle, if they're AN or what. Install should be quick and easy, it's just a matter of deciding what to do and what parts to do it.
