Does Ford use the CP4 pump?

Yes. Ford has used Bosch CP4 high-pressure fuel pumps on some of its modern diesel engines, most notably in the 3.0-liter Power Stroke and certain versions of the 6.7-liter Power Stroke. The exact pump variant and the model-year fit can vary by market and configuration.

Overview: what the CP4 pump is and why Ford uses it

The CP4 is Bosch’s high-pressure pump used in common-rail diesel systems. It generates the very high fuel pressures required by modern direct-injection engines and is commonly paired with electronic regulation to deliver precise fueling. Ford adopted CP4-based systems on select diesel engines to enable higher efficiency and power, though not all Ford diesels use CP4. Some markets and model years rely on alternative HPFP designs, so the CP4 fit is not universal across Ford’s lineup.

Ford engines known to use CP4

Examples of Ford diesel engines that have used CP4-family high-pressure fuel pumps include:

• 3.0L Power Stroke (Scorpion) in recent F-150 and certain Transit models (introduced around 2018 and continuing in later years).


• 6.7L Power Stroke in Ford Super Duty trucks (introduced in 2011 and continuing in current generations) — variations of the CP4 family have been associated with this engine over its production life.

Note: The exact CP4 variant (for example, CP4.1 vs. CP4.2) and the production years can vary by market and by specific engine revision. Some Ford diesel variants in earlier years used different HPFP designs.

Maintenance and reliability considerations

CP4 pumps have drawn attention in the diesel community for potential failure modes when fuel quality or filtration is poor. Proper maintenance is important to minimize risk and ensure longevity of the high-pressure system.

• Ensure clean diesel fuel and use high-quality fuel filters to prevent abrasive contaminants from reaching the pump.


• Adhere to Ford’s recommended service intervals for fuel filters and related fuel-system components.


• Be aware of symptoms that can indicate HPFP or fuel-system issues, such as rough running, loss of power, misfires, or warning lights.


• Check for any manufacturer service bulletins or recalls specific to your engine and VIN, as HPFP-related updates can occur.

For prospective buyers or current owners, confirming the exact pump type for your engine and year is important, since variations exist across markets and model revisions.

Summary

Ford does use CP4 high-pressure fuel pumps on some contemporary diesel engines, most notably the 3.0L Power Stroke and certain 6.7L Power Stroke configurations. The CP4 adoption is not universal across Ford’s entire diesel lineup, and the precise pump variant can differ by market and model year. Always verify the specific engine, year, and VIN in official service documentation to determine the exact fuel pump configuration.

What year do Fords have a CP4 pump?

The CP4 pump was standard on 2011 to present versions of the Ford 6.7-liter Powerstroke.

Is Ford still using CP4?

The part in question is Bosch's CP4 RP7 fuel pump, which Ford introduced during the 2020 model year run of F-Series Super Duty trucks, and ran through the 2021 model year, when Ford replaced it in production with an updated RP8 unit.

How much is the Ford CP4 payout?

The settlement provides a $50 million fund, with $30 million specifically allocated to compensating class members who paid out of pocket for a repair of their high-pressure fuel pump (the CP4 pump).

What year Ford 6.7 to stay away from?

The 6.7 Powerstroke years to avoid are primarily 2011-2014 due to issues with the turbocharger's ceramic bearings, an early plastic oil pan on some models, and other first-generation problems. While 2020-2021 models had some 10-speed transmission issues, they are less problematic and have a stronger engine bottom end than earlier models.

Years to avoid

• 2011-2014: These are generally considered the least desirable years due to several first-generation issues. 
  • Turbocharger: Early models used ceramic bearings in the turbo which are prone to failure; a switch to steel bearings occurred later in this generation. 
  • Oil pan: Some early 2011 models had a plastic oil pan that could leak, but this was changed to steel in 2012. 
  • Other problems: These years also had potential issues with the CP4 fuel pump, radiators, and the crankcase ventilation system. 
• 2020-2021: These models are best avoided for their problems with the 10-speed transmission. 
  • The 2022 model year and newer have an updated 10-speed transmission that is more reliable.

More reliable years 

• 2015-2019: This second generation is often recommended because it addressed many of the first generation's issues, including the switch to a more robust steel-bearing turbo. 
• 2022 and newer: These models offer a stronger bottom end and have an updated and more reliable 10-speed transmission.
