198512 - Miller 198512 Fuel Level Sender Assembly for 22.5-Inch Tanks

Precision Fuel Monitoring for Industrial Welders

The Miller 198512 Fuel Gauge Sender is a critical replacement component designed specifically for Miller engine-driven welding machines equipped with 22.500-inch deep fuel tanks. In the demanding environments where industrial welders operate—from remote pipeline sites to heavy construction zones—knowing exactly how much fuel remains in your generator is vital for planning work shifts and preventing costly downtime due to fuel exhaustion. This sender unit acts as the communication bridge between the physical fuel level in the tank and the gauge on your machine's control panel.

Engineered to Miller's exacting OEM specifications, this sender assembly is built to withstand the rigorous vibration, thermal cycling, and harsh conditions typical of diesel and gasoline engine-driven equipment. Unlike universal senders that may require calibration or modification to fit, the 198512 is pre-calibrated for the specific geometry of a 22.5-inch deep tank. This ensures that the float arm travel corresponds perfectly to the tank's capacity, providing linear and accurate readings from full to empty.

Failure of a fuel sender can lead to operational inefficiencies, such as operators stopping prematurely to refuel or, worse, running the engine dry and requiring a fuel system bleed. By installing a genuine Miller 198512, maintenance teams ensure that the resistance values sent to the gauge are within the factory-specified range. The unit typically features a robust mounting flange and corrosion-resistant materials to ensure longevity even when exposed to modern fuel additives. Whether you are refurbishing an older Big Blue or maintaining a fleet of Trailblazers, this part restores the reliability of your fuel monitoring system.

Installation is straightforward for technicians familiar with engine drive maintenance. The unit is designed to drop directly into the existing tank opening, aligning with the standard bolt pattern used on Miller tanks of this depth. Trusting OEM parts for fuel systems not only guarantees fitment but also maintains the safety and integrity of the equipment's fuel containment system.
