Type: Universal Intank Fuel Pump Fuel: Gas Horsepower: 500HP+ Flow Rate: 400LPH Outperforms all current market in-tank fuel pumps Designed for engines with more than 500HP Award-winning OE technology Dual channel turbine design for maximum efficiency under high pressure and high temperature applications Made in USA by TI Automotive (formerly known as  Walbro) The F90000262 requires modifications to system wiring, fuel lines and the fuel module, and should be professionally installed. 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 500hp. Designed for gasoline applications. Designed for E85 use part number TIA485 Instead 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.
