Walbro 450LPH – TI Automotive TIA485-2 Fuel Pump

The innovative design of the DCSS 39/50 high flow in-tank fuel pump 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.
