301598 - Miller EnPak A30 & Bobcat 200 Auxiliary Fuel Pump Kit

Technical Overview of the Miller 301598 Auxiliary Fuel Pump Kit

The Miller 301598 Auxiliary Fuel Pump Kit is a specialized engineered component designed to enhance the operational flexibility of the EnPak® A30 and Bobcat™ 200 Air Pak™ power systems. In the context of industrial mobile service units and work trucks, the integration of power equipment with the vehicle's fuel infrastructure is a critical design consideration. This kit addresses the hydraulic and mechanical challenges associated with fuel delivery when the power unit is mounted at a different elevation than the fuel source.

The primary technical specification of this kit is its 50-inch lift capability. In fluid dynamics within automotive and industrial applications, "lift" refers to the vertical distance a pump can raise fluid from the reservoir to the intake point. Many standard mechanical fuel pumps have limited lift capacities, restricting where a generator or compressor can be mounted relative to the fuel tank. By providing 50 inches of lift, the Miller 301598 allows for chassis-mounted fuel tanks to reliably supply roof-mounted or deck-mounted EnPak units, overcoming the gravitational head pressure that would otherwise starve the engine of fuel.

Reliability is paramount in MRO (Maintenance, Repair, and Operations) environments. The EnPak A30 and Bobcat 200 Air Pak are often the heart of a service truck, providing compressed air, electrical power, and welding capabilities. A failure in the fuel delivery system renders these critical assets useless. This genuine Miller OEM part is manufactured to meet the exact flow rate and pressure requirements of the compatible Kubota or Kohler engines found in these units. Unlike generic fuel pumps which may provide inconsistent pressure—leading to lean running conditions or carburetor flooding—this kit ensures the engine receives the precise fuel volume required under varying load conditions.

Installation of the 301598 kit facilitates a seamless integration into the vehicle's ecosystem. It allows fleet managers and truck upfitters to design more efficient layouts, placing fuel tanks in the safest or most convenient locations without being constrained by the stock fuel pump's limitations. This component is essential for optimizing the duty cycle and autonomy of mobile workstations.
