I've been doing a fair amount of research towards a DIY water/alky setup and am still undecided on the solenoid valves and nozzles. I have decided on the pump and overall design. I know some of you are using NOS solenoids but I don't know if you're using Nitrous or Fuel solenoids. Can you use either? I've also looked at a bewildering assortment of industrial solenoids. Any suggestions/advise would be appreciated.
