257484 - Miller 12-Gallon Fuel Tank Assembly with Sender and Vent

Genuine Miller Replacement Fuel Tank Assembly

Maintain the operational integrity and safety of your Miller engine-driven welding equipment with the genuine Miller 257484 Fuel Tank Assembly. Designed specifically for compatibility with select Miller industrial welders, this 12.0-gallon fuel tank is a critical component for ensuring your machine runs smoothly during long shifts on the job site. When your fuel system is compromised by cracks, leaks, or internal contamination, replacing the entire tank assembly is often the most reliable solution to prevent downtime and potential hazards.

This assembly is not just a bare tank; it comes pre-equipped with essential components to streamline the replacement process. Included in the assembly are the vent valve and the fuel level sender. The pre-installed sender unit ensures that your fuel gauge provides accurate readings immediately after installation, eliminating the need to calibrate or transfer old, potentially faulty sensors. The vent valve is crucial for maintaining proper pressure equilibrium within the tank as fuel is consumed and as temperatures fluctuate, preventing vacuum lock or dangerous pressure buildup.

Constructed to Miller's rigorous OEM specifications, this fuel tank offers the durability required for harsh industrial environments. Whether your equipment sits on a construction site, a pipeline project, or a fabrication yard, the materials used in this tank are resistant to the vibrations, impacts, and chemical exposure typical of heavy-duty welding operations. Using genuine OEM parts like the 257484 ensures that the mounting points align perfectly with your machine's frame, avoiding the modifications often required by aftermarket generic tanks.

Investing in a complete assembly saves valuable technician time. Instead of sourcing individual gaskets, valves, or senders, this all-in-one solution allows for a direct "drop-in" replacement. Ensure your welding generator is ready for the next project with a fuel system that meets factory standards for safety and performance.
