Whether you're upping the boost or stroking your block - more fuel is a MUST!
The innovative design of the DCSS 39/50 features a single impeller with two parallel rows of turbine blades. Designed for E85 or gasoline applications. 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 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.
