213858 - Miller Diesel Fuel Filter 5/16 In-Line for Bobcat and Trailblazer

Reliable Filtration for Industrial Diesel Engines

The Miller In-line Diesel Fuel Filter 213858 is a critical maintenance component designed to ensure the longevity and performance of your industrial welding equipment. As a genuine OEM part, this filter is engineered to meet the exact specifications of Miller Electric's heavy-duty engine-driven welders. In the harsh environments where these machines operate—from dusty construction sites to remote pipelines—clean fuel is essential for reliable operation. Contaminants in diesel fuel can lead to clogged injectors, reduced power output, and eventually, costly engine failure. This filter acts as the first line of defense, trapping particulates before they can reach sensitive engine components.

Broad Engine Compatibility

One of the key advantages of the 213858 filter is its versatility across a wide range of power plants used in Miller equipment. It is the specified replacement for diesel engines manufactured by Kubota, Perkins, CAT (Caterpillar), Deutz, and Mitsubishi that are integrated into Miller welding generators. Whether you are servicing a fleet of mixed equipment or a single dedicated rig, ensuring you have the correct filtration for these specific engine brands is vital for maintaining warranty compliance and operational efficiency.

Technical Specifications and Fitment

This in-line filter features standard 5/16-inch (approx. 8mm) inlet and outlet connections, allowing for quick and secure installation into the fuel line without the need for adapters. It boasts a filtration rating of 125 to 175 microns, a range specifically chosen to balance flow rate with effective particulate removal for these specific diesel applications. It is compatible with a comprehensive list of Miller machines, including the Bobcat 250 Diesel, the entire Trailblazer diesel series (300 D NT, 301 D, 302 Diesel, 325 Diesel), and the heavy-industrial Big Blue lineup (300, 350 Pipe Pro, 400 KX, 400 Pro, 450 Duo CST, and 500 Eco Pro). Regular replacement of this filter is a small investment that yields significant returns in machine uptime and reliability.
