I don't have an alchy kit installed, but back when I was torturing myself with a seventh injecter setup, I used an NOS fan spray nozzle. What I did was get a 1/8th NPT nipple, dilled the uppipe for the nipple and tapped it with a 1/8th NPT-27 tap. Screwed the nipple to temporarily hold the nipple in the up pipe. Used a MIG welder to weld the nipple to the pipe. I the trimmed the nipple on the in side and out side of the uppipe to size, and gound the inside smooth. The inside diameter of the nipple was just the right size to tape with a 1/16th-27 tap, wich is the correct size for the fan spay nozzle. For the fan spay nozzle, this setup was bullet proof, and is what I will use if i ever get around to doing an alchy setup. I have finally ponied up for the right size injectors, so i have since removed the seventh injector.
