290133 - Miller Fuel Level Sender Replacement Kit for Bobcat and Trailblazer

Miller 290133 Fuel Gauge Sender Kit Overview

The Miller 290133 is a specialized Fuel Gauge Sender Kit designed to replace the now-obsolete part number 238061. This component is critical for the accurate monitoring of fuel levels within Miller engine-driven welding generators. As an OEM (Original Equipment Manufacturer) part, it is engineered to meet the specific electrical resistance values and physical dimensions required by the fuel gauges found on Miller Bobcat and Trailblazer series machines. The kit includes the sender unit itself along with the necessary gasket to ensure a proper seal against the fuel tank, preventing hazardous leaks and ingress of contaminants.

Technical Compatibility

This sender kit is verified for use with a broad spectrum of Miller industrial engine drives. It supports various engine configurations, including gasoline, diesel, and EFI (Electronic Fuel Injection) models. Specifically, it fits the Bobcat 250 series (equipped with Kohler, Subaru, or Kubota Diesel engines) and the Trailblazer 275 and 302 series (Kohler, Subaru, and Kubota Diesel variants). It is also compatible with specific 3-phase Bobcat models. Technicians should verify fitment against the machine's serial number to ensure this revision matches the specific fuel tank assembly of the unit being serviced.

Construction and Durability

Engine-driven welders are often subjected to high vibration, thermal cycling, and rough transport conditions. The Miller 290133 sender is constructed to withstand these environments without losing calibration or structural integrity. The float mechanism and variable resistor are housed to resist corrosion from modern fuel blends. Replacing a faulty sender is a standard maintenance procedure that restores the operator's ability to manage refueling intervals effectively, thereby maintaining job site productivity.

Installation Notes

Installation involves accessing the top of the fuel tank, removing the old unit, cleaning the mating surface, and installing the new sender with the provided gasket. Proper torque should be applied to the mounting screws to compress the gasket evenly without damaging the tank flange. This kit provides all the necessary hardware components to perform a complete replacement of the sending unit.
