DW has engineered their fuel pumps to maximize flow at higher pressures. By designing the armature for torque bias, delaying pressure relief activation, and maximizing impeller efficiency, DW has created a line of pumps with an extremely flat flow curve. Higher flow at higher pressure delivers the fuel your engine demands.

  • Application Specific Fitment
  • Quality Testing
  • Ethanol Compatible
  • In-Tank, In-Line, Compact, Brushless, Pump Modules
  • 3-Year Warranty

All DW pump designs go through 1,000 hours of endurance bench testing in a number of fuels to find and eliminate common modes of failures. Upon success, the pump design is in-car tested for several months in real-world conditions before production is approved. Each DeatschWerks fuel pump is flow tested at pressure to make doubly sure that it meets DW’s high standards of performance before it is labeled and packaged.


DW has specifically engineered its pumps for use in Ethanol

  • Composite Impeller – made of a lightweight composite that is both efficient and impervious to the corrosive nature of ethanol.
  • Encapsulated Armature – DW pump motor armatures are fully encapsulated to protect the copper windings from ethanol deterioration.
  • Carbon Commutators and Brushes – Resists aggressive fuels, reduces electric draw, and leads to a much longer life especially in high-heat and high-pressure conditions.

Whether you prefer Pump Gas, Race Gas, or Ethanol, these design features translate to a more dependable longer-life fuel pump.
