DW440 Brushless Fuel Pump Dual Speed

The DW440 Brushless Fuel Pump Dual Speed by DeatschWerks is engineered for serious performance enthusiasts and motorsport builders who demand reliability in high-output fuel delivery systems. Whether you're tuning a naturally aspirated engine or running forced induction, this brushless pump addresses the critical challenge of supplying adequate fuel volume at varying engine loads without sacrificing efficiency or longevity. Built for street, strip, and circuit applications, the DW440 eliminates the parasitic drag and heat generation typical of brush-type pumps, making it the go-to upgrade for builders who understand that fuel delivery is foundational to power and drivability.

The brushless motor design significantly reduces internal friction and electrical noise compared to conventional pumps, translating to cooler fuel temperatures and extended component lifespan under sustained high-load conditions. The dual-speed feature allows the pump to operate efficiently across the RPM range—running at lower speed during cruise to minimize heat and power draw, then automatically ramping to full output under acceleration and boost demand. This intelligent speed modulation preserves fuel quality, reduces vapor lock risk on hot days, and improves overall system reliability. The compact footprint (6.5 x 3.2 x 6.7 inches) and lightweight design (1.8 lbs) facilitate integration into tight engine bays and minimize unsprung weight transfer during dynamic driving.

This pump is ideal for tuners building turbocharged, supercharged, or naturally aspirated platforms requiring consistent fuel pressure above OEM specification, as well as vintage and custom applications where original equipment falls short. Installation typically requires a quality fuel pressure regulator and appropriate feed and return line sizing to maximize the pump's flow capability and prevent excessive system pressure spikes. Proper tuning integration—including fuel pressure curves matched to boost levels—ensures the DW440 delivers its full potential while maintaining component longevity and drivability across all throttle positions.
