Eliminate CP4 Failure – Upgrade to the Proven 6.7F-DCR-1 DCR Conversion
If you own a 6.7 Powerstroke, you already know the truth:
the factory CP4 pump is a ticking time bomb.
The S&S Diesel 6.7F-DCR-1 CP4 to DCR Conversion Kit is the permanent fix, replacing the failure-prone CP4 with a highly durable DCR (Diesel Common Rail) pump engineered for reliability, performance, and long-term protection.
This is not just an upgrade — it’s insurance against catastrophic fuel system failure that can cost $10,000–$15,000+ in repairs.
Why the CP4 Pump Fails (And Why You Need This Kit)
The OEM Bosch CP4 pump is widely known for:
- Sudden internal failure
- Metal contamination throughout the fuel system
- Injector, rail, and line destruction
- Complete system replacement costs
When it fails, it takes everything with it.
The 6.7F-DCR-1 conversion eliminates that risk completely.
What Makes the DCR Pump Superior
The DCR pump used in this kit is a next-generation solution, co-developed by S&S Diesel and PurePower Technologies.
Key Advantages:
- Two-Piston Design – More stable, more reliable than CP4
- Patented Eccentric Drive Technology – Reduces internal wear

Already Experienced a CP4 Failure? Read This Before Installing
If your CP4 pump has already failed, simply installing the 6.7F-DCR-1 conversion kit alone is NOT enough.
When a CP4 fails, it typically sends metal shrapnel throughout the entire fuel system, contaminating:
- Fuel injectors
- Fuel rails
- High-pressure lines
- Return system
- Fuel tank and low-pressure system
This is known as a catastrophic fuel system failure, and if not properly addressed, any remaining contamination can destroy your new DCR pump and injectors almost immediately.
The Correct Fix After CP4 Failure
To properly repair a failed system, you must perform a complete fuel system replacement, which includes:
- New injectors
- New fuel rails
- New high-pressure lines
- Thorough system flushing or replacement of contaminated components
Skipping this step can lead to repeat failure and thousands in additional damage.
