Keep the fuel system in your Ford 6.7L Powerstroke protected from potential CP4 pump failure by installing the S&S Diesel Gen2.1 CP4 Disaster Prevention Bypass Kit CP4-6.7F-BP-G2.1 from Guaranteed Auto Parts. S&S Diesel Motorsport, creator of the original Disaster Prevention Kit for the 6.7 Powerstroke, is at it again with a much-improved second generation kit. Since its debut in 2016, the original S&S 6.7L Powerstroke CP4 Bypass Kit (Disaster Prevention Kit) has safeguarded thousands of injectors from CP4 debris. Being a company founded by fuel system engineers, S&S Diesel Motorsport has the ability, and responsibility, to offer the best solutions to fuel system problems. While the original bypass kit offers really good protection from a CP4 failure, the last four years have given the S&S engineers plenty of time to discover and eliminate potential problems.
 
The S&S Diesel Motorsport Gen2.1 6.7L Power Stroke CP4 Bypass Kit features all quick connect lines that eliminates the need for cutting the factory supply line, which is a debris introduction point, especially if the cut is not thoroughly deburred. It also eliminates the need to use a compression fitting, which is a potential leak point. The OE-style quick connect lines also eliminate any threaded joints that are further leak points and have the potential of generating debris during install.
 
The main task of both kits is to supply the CP4 case and the metering unit/plungers independently with clean, filtered fuel, and to reroute case fuel back to the tank. There are two major improvements in how the Gen2.1 kit accomplishes this. The Gen2.1 fuel supply is split off into two separate lines 25-inches from the CP4, which will eliminate the chance of contaminated case fuel back-feeding into the clean fuel supply line. The original bypass kit splits off within an inch of the pump, and is more susceptible to debris back-feeding, if the CP4 failure produces enough debris to clog the fuel return system. The other improvement is what happens to the debris when it exits the pump case. The Gen2.1 kit features a billet return filter head that accepts a readily available Donaldson P550943 spin-on fuel filter which prevents debris from reaching the tank, fuel lines, and supply pump. Previously, victims of a CP4 failure, with the good fortune of having an original bypass kit installed, would still need to drop the tank and deal with all of the debris created by the failed CP4.
 
One would think that major improvements would come at a major price increase. Having a clear understanding of common rail diesel fuel systems, and decades of OE engineering experience, enabled the engineers at S&S to make improvements without increasing production costs. Thanks to efficient design and use of material, the S&S Diesel Motorsport Gen2.1 6.7L Power Stroke CP4 Bypass Kit delivers even more value than the original. Best of all, there is no longer a need to distinguish what year the truck was made, the new Gen2.1 Bypass Kit will fit the Ford F250/F350/F450/F550 Super Duty pickup trucks with the 6.7 Powerstroke Diesel engine.

The perfect casual layer—unbelievably soft!
Size: Large, Color: Burgundy
I am seriously impressed with this hoodie. It’s made from a lightweight jersey material that feels just like a broken-in, high-quality t-shirt. It’s perfect for those transitional weather days when a heavy fleece hoodie would be too warm, or for just lounging around the house. The fit is spot on—not too baggy but with enough room to move comfortably. It washes really well without shrinking or losing its shape. For the price, you absolutely cannot beat the value. I'll definitely be buying a few more colors!

The Perfect Hoodie for Warm Weather Comfort
Size: XX-Large, Color: Black
I've been on the lookout for something exactly like this... a hoodie with the look and feel of a sweatshirt, but without all that heavy fleece that can become uncomfortable when temperatures rise. This Amazon Essentials Lightweight Jersey Pullover Hoodie turned out to be just the solution I needed. Right out of the package, I noticed the material felt soft and airy, like a premium-quality T-shirt rather than a traditional hoodie. The lightweight fabric hits just the right balance: thin enough to remain cool and breathable, yet substantial enough to give you that hoodie vibe you're after. This makes it especially great when the weather is too warm for your thicker hoodies but still a bit too breezy for just a tee. The fit is exactly what I was hoping for... comfortable without being baggy, and relaxed enough to allow easy movement. It drapes nicely, so it never looks awkward or ill-fitting. The hood itself is perfectly sized—not overly bulky, but still practical if you need a bit of coverage. No shrinkage when washed and didn't fade. I've found this hoodie to be ideal for casual days around town, lounging, or even traveling. It layers well, making it versatile for spring, early summer evenings, or warmer fall days. If you're looking for something comfortable, lightweight, and stylish enough to pull off the hoodie look in warmer weather, this is absolutely worth picking up.

My new favorite hoodie!
Size: XX-Large, Color: Charcoal Heather
I love this, this is my new go-to hoodie! It's very soft and breathable, it's roomy and comfortable, and it's not too heavy. I've washed it a few times and it's held up well. For the price, you really can't go wrong. I'll probably end up buying a couple more colors.

Sleeves are too short
Size: Large, Color: Black
Good quality about as thick as heavy t shirt. The only issue is the sleeves are a tad short which is a bit disappointing. Not sure I will buy this again. I’m 5-7 175 and ordered a large and it fits well. Just a smidge oversized like I prefer.
