215984 - Miller 215984 In-Line Fuel Filter for Bobcat, Trailblazer & Legend Welders

Reliable Fuel Filtration for Miller and Hobart Welders

Ensure the longevity and reliability of your engine-driven welding fleet with the Miller 215984 In-Line Fuel Filter. This high-quality replacement part is engineered to meet the exact specifications of Miller Electric's gasoline-powered equipment. Whether you are operating a Miller Bobcat, Trailblazer, or Legend, this filter provides the essential filtration necessary to protect sensitive engine components from the harmful effects of contaminated fuel.

The 215984 filter is designed for 0.250-inch (1/4") fuel lines, a standard size for many industrial small engines. It is verified to fit specific Kohler, Onan, and Subaru (Robin) engines, including the Kohler CH23 often found on Miller Legend and Bobcat models. The in-line design makes installation straightforward and quick, minimizing maintenance downtime so you can get back to welding. Its robust construction withstands the vibration and heat typical of engine-driven welder environments.

Using clean fuel is non-negotiable for maintaining the precise governor control required for stable welding output. A restricted fuel filter can cause engine surging, which translates to fluctuations in voltage and amperage at the arc. This genuine Miller part ensures optimal flow rates while effectively capturing particulate matter that could clog jets or damage internal engine surfaces. It is an essential item for any preventive maintenance kit.

This filter is sold individually as a complete unit ready for installation. It is also compatible with select Hobart Champion™ welders equipped with similar gasoline engines. Verify your machine's serial number or engine model to ensure correct fitment, but for most gas-powered Miller industrial welders utilizing 1/4" lines, this is the factory-specified replacement.
