S&S Gen 2.1 CP4 Disaster Prevention Kit | 2011+ 6.7 Powerstroke
Part#:
Description
When the CP4 on a 6.7 Powerstroke comes apart, the metal it sheds goes straight into the rails and injectors. That turns a pump replacement into a full fuel system job. The S&S Gen 2.1 kit feeds the pump clean fuel on its own line and sends the fuel from the pump case back toward the tank through a filter, so the debris is caught instead of circulating through the rest of the system.
- Fits: 2011 and newer 6.7 Powerstroke. One part number covers every year.
- Part number: CP4-6.7F-BP-G2.1
- Install: every connection is an OE style quick connect. You do not cut the factory supply line and there are no compression fittings.
- Return filter: billet head that takes standard spin on filters. Comes with a Donaldson P550943, 9 micron at 99% efficiency.
- Emissions: CARB compliant, EO D-756-6.
- Made in: USA.

What Changed From The First Kit
S&S built the original disaster prevention kit for the 6.7 Powerstroke in 2016. The Gen 2.1 fixes the weak points they found in it.
- No cutting. The first kit had you cut the factory supply line and use a compression fitting. A cut that is not deburred well puts debris in the line, and the fitting is a place to leak. Gen 2.1 uses quick connects everywhere.
- The supply splits 25 inches from the pump. The original split within an inch of the CP4. If a failure made enough debris to clog the return, dirty case fuel could push back into the clean supply. Splitting it farther away closes that door.
- The debris gets filtered. A return filter catches what comes out of the pump case before it reaches the tank.
Other Things It Does
S&S testing shows the kit improves CP4 output past 3,000 RPM, and it can give you more range to get off the road if the pump does start to fail.
