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).

A little snug on the thighs
Size: Medium, Color: Multicoloured G (5-pack)
Super comfy, soft and thin. For reference, I'm 5'6", 135, athletic build. I bought medium. I almost returned them because I thought they were a bit too snug on my thighs, and my thighs are not large at all. I was concerned about panty lines under snug clothing. But, because they're thin, I figured they would probably stretch, so I kept them. So far, I've only worn them under a night shirt, but they're super comfortable and they dont ride up at all. Very nice, but if your thighs are a little thick, you probably won't like them.

Functional + Sexy
Size: Small, Color: Multicoloured E-(5-pack), Size: Small, Color: Multicoloured E-(5-pack)
Not only do these feel good, my husband can’t keep his hands off me. They fit so good and are soft. I change into these to sleep but also just use them as shorts to wear around the house. They’re comfortable and don’t slide around. I got a size small and I’m 100lbs.

Finally!
Size: X-Large, Color: All Black D (5-pack)
Finally, comfortable underwear that don’t end up giving me a wedgie. I have a round booty and most cuts of underwear end up shifting as I walk and sit. The hem of the underwear comes right under my cheeks and the lightweight material ensures there’s no panty line and no shifting to where I don’t want them! I’m definitely purchasing more.

They’re fantastic!!!!
Size: X-Large, Color: Multicoloured E-(5-pack)
My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly.
The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.
