Is this the general idea?

Get a ketchup bottle with the witch-hat cap; drill a small hole in the bottom; fill it with your solution; invert it where the tip of bottle is in a stream from your spray bar; low pressure sucks out small amounts of your solution continuously. If it is, you could alway get a bottle with and rubber tube that has a nipple on the end (like the needle used to fill basketballs, etc). That could give you more flexabiltiy in mounting location.
