OVERVIEW

Restore Your Welder's Reliability with Miller OEM Parts

Keep your engine-driven welder running at peak performance with the Miller 266531 12-Gallon Fuel Tank Assembly. Fuel leaks or contamination can sideline your most valuable equipment, costing you time and money. This authentic Miller Electric replacement part is the exact specification required for many late-model Bobcat and Trailblazer welders, guaranteeing a secure fit and leak-proof seal. The 12-gallon volume is optimized to balance weight and runtime, ensuring your crew can work through the day.

The 266531 assembly offers a complete repair solution. It arrives with the fuel sender unit and vent valve pre-installed. This saves you the hassle of salvaging old, potentially damaged components from your previous tank or purchasing them separately. The fuel sender is calibrated to work seamlessly with your welder's existing fuel gauge, while the vent valve manages internal pressure changes caused by temperature fluctuations and fuel consumption. The tank body is molded from robust, impact-resistant plastic that stands up to UV exposure and the rigors of transport.
