In an HEUI system, there is no high-pressure fuel pump - the fuel pressure is generated inside the injector, by stepping up the pressure generated by the High-Pressure Oil Pump, or HPOP. Fuel is supplied along a common rail under low pressure. The HPOP generates high-pressure oil flow, driven by a gear underneath the front cover.High-Pressure Oil Pumps: Volume, Not Pressure. Instead of a conventional injection pump, HEUI systems use a high-pressure oil pump.
