A vehicle battery tray that, along with a vehicle battery cover, is part of a vehicle battery enclosure that houses and protects a vehicle battery pack. The vehicle battery tray is a modular assembly that uses standardized parts, such as frame components and tray components, and can easily be adapted during manufacturing to fit different size battery packs for different applications and customers. In one example, two or more tray components are joined together to form a battery compartment, whereas in a different example each tray component forms a battery compartment on its own. The frame components may be made from an extruded aluminum-based material, and the tray components may be made from a casted aluminum-based material or a molded plastic material.

A fill tube assembly is for a casting mold. The fill tube assembly includes a fill tube having a tubular member with a receiving end, a mold-engaging end and an intermediate portion. The mold-engaging end has a tapered flange radially extending therefrom, the remainder of the tubular-member has a substantially uniform cross-section. A clamping assembly is structured to maintain a substantially leak-proof seal at the fill tube, casting mold interface while accommodating dimensional variations. The clamping assembly includes a gasket, a load ring, a clamping plate and a pre-load gap between the clamping plate and the casting mold and optionally includes a dimensional compensating ring. When tightened, the clamping plate biases the load ring against the flange thereby distributing a uniform load against the casting mold, compressing the gasket therebetween while narrowing the pre-load gap to accommodate dimensional variations. A method of use is also disclosed.
