What year do Fords have CP4 pumps?
The short answer: CP4 high-pressure fuel pumps are associated with Ford's diesel engines and first appeared with the 2011 model year 6.7L Power Stroke; they are not used on Ford’s gasoline engines.
In more detail: The CP4 is a Bosch common-rail high-pressure pump used in Ford's diesel injection systems. The exact years and models depend on the market and configuration, but the best-known and most widespread application in North America is the 6.7L Power Stroke used in F-250/350/450 trucks since 2011. Some later diesel variants, such as the 3.0L Power Stroke in newer Super Duty/Heavy Duty setups, have used CP4 variants as well. If you own a Ford with a diesel engine and want to confirm whether it uses CP4, check the service data for the exact pump model or VIN-encoded engine specification.
Ford CP4: Engines and model years it has appeared
The following list highlights the main Ford engines and model years commonly equipped with CP4 high-pressure pumps. Note that exact configurations can vary by market and option package; always verify with the vehicle's VIN or service documentation.
- 2011–present: Ford 6.7L Power Stroke diesel (F-250/350/450 Super Duty) — Bosch CP4 high-pressure pump in the common-rail system.
- 2018–present: Ford 3.0L Power Stroke diesel (various Super Duty/F-150 variants in some markets) — used with a CP4-based high-pressure injection system in certain configurations.
- Note: CP4 pumps are not used on Ford gasoline engines (such as EcoBoost or V8 gasoline engines); those use different fuel-system designs.
Concluding: The CP4 pump has been Ford’s go-to high-pressure pump in its diesel lineup for more than a decade, with the 6.7L Power Stroke being the most prominent example. Always verify for a given vehicle since Ford markets and engine configurations can vary by country and trim level.
CP4 vs CP3: Understanding the difference
CP4 is a higher-pressure, common-rail fuel pump compared to the older CP3 design used in many earlier diesel engines. CP3 systems typically deliver lower maximum rail pressures than CP4, which influences fuel-system design, reliability considerations, and the potential consequences of contaminants or failures. Ford’s diesel lineup has migrated largely to CP4-based systems for modern efficiency and emissions requirements.
Why CP4 matters for owners
CP4 failures have been a major topic among Ford diesel owners because a malfunctioning pump can cause severe engine damage if metal debris enters the fuel system. Symptoms can include hard starting, rough running, misfires, loss of power, or sudden fuel pressure drops. Because repairs often involve the fuel-injection system and engine internals, costs can be substantial. Vehicle owners should maintain clean fuel, replace filters at recommended intervals, and consult a dealer if a CP4 worry arises.
How to verify if your Ford has CP4
To confirm whether a specific Ford model uses CP4, use the steps below. This is especially important for diagnosing pump-related concerns or ordering replacement parts.
- Check the vehicle’s VIN and build sheet or service data for the engine’s fuel-system configuration and pump model (CP4 vs CP3).
- Inspect maintenance documentation or the service bulletin for your engine; look for references to CP4 or CP4.2 in the high-pressure pump specifications.
- Contact a Ford dealer or a qualified diesel tech with your VIN to verify the exact pump model and compatibility with replacement parts.
In practice, most Ford diesel owners will be dealing with CP4 when working on the 6.7L Power Stroke family and related diesel variants introduced in the 2010s and beyond.
Summary
Ford’s CP4 high-pressure fuel pumps have primarily appeared in its diesel engines since the 2011 model year, most notably in the 6.7L Power Stroke. Gasoline Ford engines do not use CP4. For any given vehicle, verify the pump type using the VIN or service data, as configurations can differ by market and trim. Understanding whether your Ford has CP4 is important for maintenance and troubleshooting, particularly given the pump’s role in the high-pressure fuel system.
