Abstract
An insert is provided for a liquid inlet at the top of a tank not having a fill pipe for preventing liquid from a nozzle spout of a diameter greater than a predetermined dimension from filling the tank, and allowing liquid from a nozzle of smaller diameter to fill the tank to very near the top. The insert has a mouth with a wide opening at the top and an opening at the bottom just large enough to receive a spout having that predetermined diameter. A throat having an internal diameter slightly greater than that predetermined dimension extends from the bottom opening. A valve closes the throat under the force of a spring and a grid prevents the nozzle spout from being inserted past the end of the throat. Connected to the valve is a structure that is engaged by the nozzle when said spout is inserted into the throat to open the valve and permit liquid from the spout to pass into the tank.
