The Delphi Diesel Electronic Unit Pump (EUP) is a robust high
pressure fuel delivery device that is a part of a high performance
diesel fuel injection system for heavy duty "cam in block" engine
applications. The EUP uses proven valve technology from Delphi's
highly successful EUI product line. It can be used in conjunction
with either Delphi's mechanical injector (single valve system) or the
Delphi Smart Injector (dual valve system) and interconnecting high
pressure fuel delivery pipe.
