DeatschWerks redesigned the DW300 to offer greater flow with no significant increase in current draw. The new DW300 pump flows 26% more at its peak and 20% more on average. The low amperage draw minimizes pump temperatures, maximizes pump life and reduces stress on OE wiring.
The increases in flow were specifically engineered for high pressures (60-90psi), where forced induction applications need it the most. Conversely, fuel flow has been limited at low pressures (30-50psi) to minimize heat generation in return fuel systems. This dual zone approach results in a flatter flow curve, which maximizes both performance and reliability for supercharged or turbocharged applications.
