Abstract
Water fill neck (16) is mounted on the intake manifold (14) of an internal combustion engine. The manifold includes an upstanding collar (22) that surrounds the lower support platform (57) of mounting body (55) of the water fill neck, and liquid accumulation spaces (50-53) are formed within collar (22) and about the lower support platform (57) of the water fill neck. The overflow from the water fill opening (18) past the gasket (37) will be retained beneath the outward projecting rim (60) of the water fill neck, thereby reducing the likelihood of liquid overflow onto the surfaces of the engine.
