I just read some more, Can I assume that the frame fuel pump,pumps fuel thru the head to the injector and this pump produces high pressure?(if so, how much) Then totally seperate from this, is the hpop which is mechanically driven. This pump, pumps oil to the injector which hydralically opens(fires) the injector?
So fuel itself, never sees the hpop? passage ways in the head flow the fuel? the hpop has its own lines to the injector top for oil?? So if hpop pumps are pumping higher and more does it open the injecter farther and longer(or just one of the above) making more power.
Also that the hpop pressure raises the fuel pressure to the thousands when its forcing it into the cylinder. The large raise in actual fuel pressure is done where? In the injector on its way to the cylinder?
