The Walbro F90000267 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.
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.
