Walbro 400lph In-tank Fuel Pump

The innovative design of the DCSS 39/50 features a single impeller with two parallel rows of turbine blades. The blades feed two high-pressure pumping channels, as opposed to a conventional single-stage pump that uses an impeller with a single row of blades at its outer edge. This innovative design results in improved hot fuel flow, as well as minimal noise and current use, resulting in efficiency that’s 20 percent higher than conventional pumps.


  • Designed for high performance engines exceeding 500hp
  • Designed for gasoline applications only
  • Outperforms all current market in-tank fuel pumps
  • Dual channel turbine design for maximum efficiency under high pressure and high temperature applications
  • Made in USA by TI Automotive (parent company of Walbro)
  • Requires modification to wiring, fuel lines and fuel module (Professional installation recommended)
