Looking for suggestions.

I need to be able to push a button and dose a very small amount (about 1/4 oz) of liquid from a container, through a one way valve, into a tank, a distance of about three feet. If necessary the container can be above the tank for a gravity feed, but it would be better if that didn't have to be the case. The tank won't be pressurized.

What this is all about? My commercial dishwasher doesn't have the rinse aid pump and those parts cost several hundred dollars from Hobart. All the pump does is pull a dose of rinse aid from a gallon jug on the floor and pump it into the tank that holds the 190F rinse water, before the rinse cycle starts. Now, I don't need rinse aid except when washing wine glasses. So I just want to manually cause rinse aid to be added to the rinse water tank only when I'm washing glasses. I assume I can use the same fitting that the pump is normally attached to.

Anyone familiar with catalogs and happen to know the parts that can be put together to accomplish this at not very high a price?
