Fuel pump

  • 10-Sep-2011 12:12 EDT

TI Automotive provides a high-performance aftermarket version of its dual-channel, single-stage (DCSS) 39/50 fuel pump for engines with more than 500 hp (373 kW). The DCSS 39/50 design 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. According to TI Automotive, this design results in improved hot fuel flow as well as minimal noise and current use, which results in efficiency that is 20% higher than conventional pumps. The DCSS 39/50 requires modifications to system wiring, fuel lines, and the fuel module and should be professionally installed.
