When discussing oil pumps, most people think of the component inside the oil pan that supplies oil to the bearings in the crankshaft, but with a high pressure system, you actually have two oil pumps on your engine. What we're talking about today is the high-pressure oil pump that supplies the fuel system.
We're going to take you through a genuine Bosch high-pressure oil pump for your Ford Powerstroke 7.3L and your Navistar International T444E and cover some questions we often see about this component.
This high-pressure oil pump or "Hpop", was designed for high pressure fuel injection systems. Bosch begin production of these in 1995, and it was an evolution driven by emissions requirements.
You see a lot of benefits from high pressure systems, including:
Low Emissions
Better Fuel Consumption
Simple and Fast Pump Replacements
On older engines, the system was a lot more complicated. These engines would have a large mechanical pump on the side of the engine and the system was almost like a mini engine with a lot of moving parts inside. All of these components created more opportunities for failure.
With a high pressure system we've gotten rid of the rotating parts, and now we have a pump that transmits its pressure via hydraulics. So instead of relying on a camshaft for mechanical transmission of power, you've got hydraulic transmission of power.
But what about failures? There are some places where you might run into problems with your high-pressure oil pump.
It runs off the same oil that the rest of the engine uses
There's a cross in operation where fuel and oil can run together
Engine burning more oil
Bad fuel mileage, worn out injectors
Fuel dilution
Oil leaks
It's important to pay attention to oil change intervals because it's all the same oil, breaking down more quickly. You might be getting more contaminants in your oil.
Your engine might be starting to burn more oil, and suddenly there might not be enough oil in the system, and you'll notice your engine running poorly. You'll be getting bad fuel mileage and your injectors can wear out more quickly.
There are a lot of opportunities for failures, if you don't have the proper lubrication.
Over time, you can also get fuel dilution. By using the same oil throughout the engine, it can get thinned out and cause problems. It's also not uncommon to have leaks. If you have a leak, you'll be dropping pressure which can affect your injection pressure, your injection timing, and all kinds of different things.
On engines like the Ford Powerstroke and the Navistar International T444E that use high pressure oil pumps, you'll likely see:
A quieter ride
Lower emissions
Better fuel economy
Higher torque
Clean and efficient fuel injection
High engine performance
