The aquamist jets came a long way since the start of this thread, they even have trick check valve jets that wont dribble after spray .....

Again, fittings, leaks, regular checkups ....

 

If anyone is interested in an HFS-3 I've got one in an unopened box from Howerton Engineering. Make me an offer.

 

Well, you can get much better nozzles on the market, I am using 2 stainless steel coolingmist super atomizing injectors CM7, which spray 10 gallons/hour ($40 each)

Also I skip the supplied lines and fittings, I am using braided hoses covered in rubber, and stainless steel fittings both from Earl's. The fittings and the hose costed me almost as much as the Aquamist kit but they worth every cent. Supplied fittings and hoses are a joke, having in mind that methanol is extremely toxic, and flammable.
