Just a simple pump up hand sprayer from Lowes. I removed the original spray nozzle and added this liquid out post. My other post wouldn't thread on at all without forcing. This one threaded on about 1-2 threads on its own. I then used a deep well socket to "guide" it the rest of the way (cut new threads). The thing I like most about this is it is small, economical and you need zero CO2 to clean your lines. Just add you cleaner of choice, agitate, hand pump, connect your beer line, open the tap. You can also use for sanitizer of course. The only draw back I see is that as soon as you connect the QD, it's active but this is solved by insuring your tap is closed when you connect it.
I apologize that I forgot to snap a photo of the unit before I removed the original spray tip.
Edit: had to relink pictures.
