A liquid dispenser adapted to fit over the open top of a container has a pump plunger connected by valving between a depending inlet and an outlet for pumping liquid from the container and a limitedly movable gauge rod is disposed in spaced parallel relation to the plunger with means securing the plunger and rod together in adjustable longitudinal relation to thereby adjustably fix the plunger stroke for metering fluid dispensed per stroke of the plunger.
