Moroso Universal Filler Cap Kit - Steel Bung

This is the Moroso Universal Filler Cap Kit, part number 85280. It's a well-built kit designed to add a filler neck and cap to your cooling system where one might not have been factory-installed, or to replace a damaged one. The steel bung gives you a solid mounting point for the new filler neck.

The kit includes a steel bung that you'll need to weld onto your radiator or coolant reservoir. Once the bung is in place, the included filler neck and cap assembly installs onto it. This setup is useful for custom builds or when you need to adapt a cooling system for a specific application. The steel construction means it can handle the heat and vibration found in an engine bay.
