Dual channel turbine design for maximum efficiency under high pressure and high temperature applications. Made in USA by TI Automotive (parent company of Walbro). All pumping components have been validated to OEM specifications for approved use in E85/flex fuel applications. 100% Authentic & Genuine Walbro/ TI Automotive E85 Racing In tank 450 LPH high pressure fuel pump.
The innovative design of the DCSS 39/50 features a single impeller with two parallel rows of turbine blades. Designed for high performance engines exceeding 750hp. Designed for E85 or gasoline applications. 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. SPECIFICATIONS 465 lph @ 40 psi and 13.5V (14.1 amps) in gasoline
Outlet diameter: 10mm (3/8")
Diameter (upper body) 39mm
Diameter (lower body) 50mm
NOTE: THE WALBRO F90000274 AND F90000267 FUEL PUMP FLOW RATES AND PHYSICAL DIMENSIONS ARE IDENTICAL. THE WALBRO F90000274 SIMPLY HAS A DIFFERENT INTERNAL RELIEF VALVE PERMITTING HIGHER FUEL PRESSURES.
