Walbro has released a high-performance aftermarket version of its
dual-channel, single-stage (DCSS) 39/50 fuel pump for engines with more
than 500 HP. The innovative design of the DCSS 39/50 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. This innovative design results in improved hot fuel
flow, as well as minimal noise and current use, resulting in efficiency
that’s 20% higher than conventional pumps.
Installation may require more work on some applications due to the larger base size when compared to a typical 255 pump. A universal install kit is available as an add-on, professional installation is recommended.
