The "older" diesel engines used fuel pressures to actuate the fuel injectors. Thus the high pressure pump was the "timing, fuel delivery, everything" of the diesel engine.
While large flowing injectors could be used to allow more flow if the high pressure pump couldn't...
Mike,
What you will probably have to do (with some development work) is develop your own regulation circuit (adjustable pressure regulator) and recirculate the fuel around the pump. That's the same system the OE pump uses. Issue arise when you have idle conditions and you are circulating the...
