TaskStar D19 Battery-Powered Fuel Transfer Pump, 13 GPM, Auto Shutoff

With two 6.6-foot hoses, the TaskStar D19 battery-powered transfer pump gives you room to move fluids between a source and equipment or a tank. It is designed for diesel, kerosene, and water, making it useful across tasks involving tractors, boats, trucks, generators, lawnmowers, and storage tanks. The 18V, 4.0Ah rechargeable battery lets you work without staying tethered to an outlet, while the included charger supports recharging between jobs.

A 13 GPM flow rate and a filter make the pump suited to planned transfer and refueling tasks where a clean, controlled setup matters. How much easier is it to work when the pump can go where the equipment is?

At a glance

The pump delivers up to 13 gallons per minute and includes an auto-stop nozzle. When the receiving tank is full, the nozzle switch pops out, a pressure switch also cuts power to the pump. These automatic shutoff features help control the transfer process, particularly when fueling equipment outdoors. The built-in filter helps remove impurities from the fuel as it moves through the system.

The rechargeable 4,000mAh battery provides up to 40 minutes of continuous use on a charge. Along with the pump, the package includes an inlet hose, an outlet hose, a filter, hose clamps, an auto-stop nozzle, a battery, and a charger. That setup brings the core parts for a cordless transfer station together in one purchase.

Size & fit

Each hose is 6.6 feet long, giving you flexibility to position the pump between a fuel source and the receiving tank. The pump is described as a universal fit for applications including boats, tractors, trucks, RVs, generators, lawnmowers, cultivators, mini excavators, and storage tanks. NPT and hose-barb connections are specified for the fittings, so match the connections to your transfer setup before beginning.

Tips for day-to-day use

For a farm, garage, boat, or outdoor work area, the cordless design makes it practical to bring the pump to equipment rather than plan the job around an outlet. Use it for diesel or kerosene transfers, or for water when the task calls for it. When pumping water, do not use the included nozzle, as the product guidance warns that it may rust. Gasoline is not a supported transfer fluid.

Before operating, charge the battery and follow the user manual. Once a fuel transfer is complete, clean fuel residue from the hose. These straightforward steps help keep the setup ready for its next intended use. If you are choosing between a pump that needs to remain near an outlet and a portable battery-powered setup, the D19’s cordless format is useful when the transfer point is away from convenient power.

Buying verdict

The TaskStar D19 brings a rechargeable power source, two 6.6-foot hoses, filtration, and an automatic shutoff nozzle into one transfer kit. It’s a great fit if you need a portable pump for diesel or kerosene around vehicles and equipment, with water transfer available using the appropriate nozzle setup. Its listed applications make it a practical choice for moving between jobs involving a tractor, boat, truck, or storage tank.
