Protect your engine from catastrophic fuel system destruction. The factory CP4 high-pressure fuel pump found on 2011+ Ford 6.7L Power Stroke diesel engines is notoriously prone to internal failure. When a CP4 pump fails, it sends sharp metal debris through the entire fuel rail system, instantly wiping out your injectors and leaving you with a massive, multi-thousand-dollar repair bill.

The Permanent CP4 Fix: S&S Diesel DCR Pump Conversion

We offer the ultimate preventative insurance policy: the DCR (Debris Control & Relief) Pump Upgrade. This heavy-duty plug-and-play conversion replaces the fragile factory CP4 pump with a robust, ultra-reliable two-plunger design built to handle lower-quality fuel and survive harsh operating conditions.

By swapping to a DCR pump, you eliminate the risk of fuel system contamination completely, securing ultimate peace of mind on the road or the job site.
