If you drive a 2011–2024 6.7L Power Stroke, there’s one weak spot that can wipe out your whole fuel system without warning: the factory CP4 injection pump.
We’ve seen it over and over—one minute the truck runs fine, the next minute it’s dead with $10,000+ in fuel system damage. If you’re not protecting your truck, you’re playing roulette with your wallet.
That’s exactly why we stock the S&S Diesel CP4 Disaster Prevention Kit (Gen 2.1). It’s clean, easy to install, and it works.
What Actually Happens When the CP4 Fails?
The Bosch CP4 has a known failure point where the internal roller lifter seizes and grenades the inside of the pump. Once that happens, it sends metal shrapnel through your fuel lines and into your:
- Fuel rails
- Injectors
- Lines
- Fuel tank
Basically, it turns your entire fuel system into scrap metal.
What the S&S Gen 2.1 Kit Does
This kit doesn’t stop the CP4 from failing—but it stops that failure from taking out the rest of your truck.
It reroutes and filters the fuel in a way that keeps the debris from ever reaching the injectors or getting recycled back into the tank. Simple concept. Solid engineering.
Key Features:
- Dual feed and return filtration (clean/case split)
- Quick-connect fittings—no cutting, splicing, or drama
- 9-micron Donaldson return filter with billet filter head
- Built for 2011–2024 trucks (yes, the newest trucks too)
- CARB compliant (EO# D-756-6)
CP4 Failure: Cost Breakdown
| Component | Cost to Replace |
|---|---|
| Injectors (8x) | $3,500–$4,500 |
| Fuel Rails + Lines | $1,000–$1,500 |
| Fuel Pump (CP4) | $1,000–$1,300 |
| Fuel Tank Flush / Replace | $500–$1,000 |
| Labor | $2,000–$4,000+ |
| Total | $8,000–$12,000+ |
Now Compare That to the Kit:
| Item | Cost | Protects What? |
|---|---|---|
| S&S Gen 2.1 CP4 Disaster Prevention Kit | $400 | Injectors, rails, fuel lines, tank, your entire wallet |
Who Should Be Running This Kit?
- If your truck is bone stock – yes.
- If your truck is deleted and tuned – yes.
- If you tow heavy – yes.
- If you rely on your truck for your business – hell yes.
This isn’t a race part. It’s insurance. The CP4 failure has nothing to do with how hard you drive your truck—some of them fail at 10K miles. Some last to 150K. The problem is, you don’t get a warning.
What Makes the Gen 2.1 Better?
S&S updated the design with quick-connect fittings to make install easier and more secure—no brass compression junk or janky hoses. The Donaldson filter is 9-micron and rated for high flow. The billet return filter head adds durability and a clean install.
Plus, the new layout works across ALL 2011+ Power Stroke models, so you don’t need to worry about different kits per year range.
