Description
Upgrade your Ford 6.7 Powerstroke with the S&S Diesel CP4 To DCR Fuel Pump Conversion Kit (6.7F-DCR-1). The CP4 has a well-earned reputation for failing without warning, creating sudden power loss, and taking out the expensive high-pressure fuel system in the process. Despite having to deal with being broken down on the side of the road, truck owners will be facing fuel system repairs that can easily exceed $10,000. The unreliable reputation is supported by recalls and lawsuits leveled at various auto manufacturers that used the CP4.2 in their production vehicles.
Direct Drop-In Solution
Removing the CP4 is the obvious solution, yet developing a durable plug-and-play CP4 replacement with OE fit and function is the game-changing catalyst S&S Diesel Motorsport® and PurePower created. Starting off with a proven Stanadyne DCR fuel pump design, a joint team of S&S and PurePower engineers developed a variant specifically for the Ford 6.7 Power Stroke that matches the CP4 output curve and does not require any calibration changes. Combining that with OE-grade braided hose and steel fuel lines gives Ford Super Duty owners a more-reliable CP4 replacement that looks and performs like original equipment.
Durable DCR High-Pressure Fuel Pump
The two-piston DCR pump is based on a compact and modular design for easy integration, has low hydraulic and acoustical noise, features ultra-fast response times, and is biofuel and low-lubricity fuel compatible. It uses a patented eccentric drive pumping technology, with pressure-lubricated cam and bushings, for increased performance, efficiency, and benchmark durability. The Fuel Control Actuator (FCA) uses high-quality corrosion-resistant components and proprietary features to prevent large debris from entering the actuator, providing exceptional robustness for longevity and durability in harsh environmental conditions. The DCR can provide a max fuel delivery of 1,250 mm3 per revolution (25 percent more than a CP4.2), producing plenty of flow for worn injectors that have high returns.
Protect Productivity
The S&S DCR Pump 6.7 Powerstroke Conversion can save Ford Super Duty truck owners $10,000 to $15,000 in fuel system repairs and impart peace of mind knowing that their daily workhorse isn't going to lay down on them.

DCR Pump Conversion Installation Notes (Additional Gaskets Needed):
2011-2016 model years require the removal of a one-time use vacuum pump gasket. Add the MAHLE B32630 Vacuum Pump Gasket to your order for a complete installation.
Per S&S Diesel, the remaining gaskets and seals can typically be re-used during installation if they are not damaged. However, the MAHLE GS33697 Fuel Injection Pump Mounting Gasket Kit is available for those who do not want to reuse the original gaskets (this kit includes the required vacuum pump gasket mentioned above).
FOR 2011-2019 MODEL YEARS PAIR THIS WITH
For those purchasing the S&S Diesel CP4 To DCR Conversion Kit that have already suffered a catastrophic failure of the CP4 pump, the XDP Fuel Contamination Kits (Without CP4 Pump) are the perfect addition to help you get your truck back up and running.

CP4 to DCR conversion
Chode (Ahwahnee, CA) | March 10th, 2026
This S&S kit went together smoothly. The fit and finish are good, directions are good. Tightening the high-pressure lines was scary, but seems to be a little quieter/smoother than the CP4. Nice pump.

DCR CONVERSION
Bradley (Gloucester, Virginia) | February 10th, 2026
I installed a DCR conversion kit on a 2018 Ford F-350 6.7L Power Stroke. This is not our first DCR conversion, and this kit continues to meet the standard we expect. Fitment was precise, components are high quality, and the installation process was straightforward with clear instructions. Based on our experience performing multiple DCR conversions, this kit is a proven reliability upgrade over the factory CP4 system. We confidently recommend it to our diesel customers.

Stress Free Install DCR Fuel Pump
Mike B. (Colorado) | December 16th, 2025
Took 9 hours for install of this S&S Diesel Performance CP4 to DCR fuel pump conversion kit on my 2016 F350 6.7-liter. Well packaged, well-written 16-page install guide with color pictures. Delivered very quickly and at a fair price in comparison to a CP4 fuel pump disaster. This purchase and installation has relieved my stress of a possible CP4 disaster and associated costs. Hope this DCR pump is the right choice and the solution to the pump issue everyone with a CP4 is concerned about.

Frequently Asked Questions
I have installed a disaster prevention kit. Do I leave that on with the dcr?
No, the prevention kit cannot remain in place when installing the S&S Diesel CP4 To DCR Fuel Pump Conversion Kit as the metering valve is different.
I have a 2021 F350 w/standard CP4. If I have the new DCR pump installed do I also have to have a disaster kit installed?
No, you do not need to install S&S Diesel CP4 Disaster Prevention Bypass Kit when installing the S&S Diesel CP4 To DCR Fuel Pump Conversion Kit
Why convert from a CP4 pump to a DCR pump?
The CP4 pump is known to be vulnerable to catastrophic failure, which can send metal debris through the entire fuel system. The S&S Diesel CP4 To DCR Fuel Pump Conversion Kit helps improve fuel system reliability and reduces the risk of total fuel system contamination.
Is this CP4 kit carb legal in California?
Yes, the S&S Diesel CP4 To DCR Fuel Pump Conversion Kit is CA legal as it C.A.R.B. EO# D-756-7.
