Choosing a high-pressure oil pump for a 7.3L or 6.0L Power Stroke means correct application, quality new or reman, and fixing the leaks that mimic a bad pump.
Match the application
The HPOP is specific to the 7.3L or 6.0L and its year. Confirm the correct pump, since the high-pressure oil systems differ between these engines.
New or quality reman
A new pump is the simplest choice; a quality reman offers value. Either way, buy a unit that can build the volume the injectors need, particularly on higher-mileage or modified trucks.
- Correct engine and year
- Quality new or reman
- Adequate volume for your setup
Rule out leaks first
Leaks in the high-pressure oil system, such as O-rings, the STC fitting, and standpipes on the 6.0L, mimic a weak HPOP. Confirm the pump is actually the problem before replacing it.
Frequently asked questions
How do I know the HPOP is bad?
Low injection control pressure and hard hot starts, but first rule out leaks in the high-pressure oil system that mimic a weak pump.
New or reman HPOP?
New is simplest; a quality reman offers value. Choose one that builds adequate volume for your setup.
What leaks mimic a bad HPOP?
O-rings and, on the 6.0L, the STC fitting and standpipes can bleed pressure and look like pump failure.
