When the high-pressure oil enters the barrel of the cylinder heads there are passages that lead from the barrel to each injector. The injection pressure is not measurable and doesn't matter anyway, because it only exists due to the spring holding the injector shut... so the injection pressure is equal to the injector pop pressure, basically. Performance Roadblocks of the 7.3L Power Stroke. I know these trucks have a pretty good cooling system from the factory, but there's no doubting that the high pressure oil system takes a toll on the oil temps. In the mid-1990s, tightening particulate matter emissions standards gave birth to the hydraulically actuated electronic controlled unit injector system we all know as HEUI.

The general guideline in the lube industry (and other chemical process industries) is the for every 10 C (18 F) increase in temperature, reaction rates double, and that means that your engine oil life is cut in half for that same temperature increase.
However, attempting to triple the power output of the engine, its fueling is a tall order. 3 can tow like a champ, gets great fuel mileage for its size, and is one of the more reliable diesel powerplants Ford has used. In the past, we've detailed the makeup of an oil-fired HEUI injector at length, but what about the other piece of the puzzle, the high-pressure oil pump? Fuel oil system flow diagram.
