ABSTRACT:
An assembly is provided for mounting a vent valve apparatus in an aperture extending through a wall of a tank containing vapor to be vented. The vent valve apparatus includes a neck keyed to engage a flat edge of the aperture to block rotation of the vent valve apparatus about its longitudinal axis relative to the tank. The vent valve apparatus further includes at least one support arm having a tab that snaps outwardly to engage a collar attached to the underside of the tank wall and retain the vent valve apparatus in its mounted position within the aperture.
