DeatschWerks DW300 In-Tank Fuel Pump Subaru 2002-2007 WRX / 2004-2007 STI


SKU dwk9-301-0791

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.

The DW Advantage

  • Flows 340 liters per hour (90 gallons per hour)
  • In-tank application specific fitment
  • Ethanol compatible
  • 3-year no-fault warranty
  • Quiet and reliable turbine impeller



Universal pump kit includes:

  • 2"x2" sock
  • Electrical connector
  • 4" of fuel line
  • Miscellaneous hardware


Technical Information
