The new 39/50 DCSS pump has been designed around the proven 39mm armature ("motor") that has been used for many years. Coupled with the proven armature are two sets of turbine blades set in parallel on a single impeller shaft. This design allow fuel to pass through two high pressure pumping channels delivering fuel in a manner to work with the high pressure demand of today's direct injection system. This pump is also compatible with E85 fuel.
