Grab the AFE DFS780 Fuel System with Full Time Operation for your 6.7L Cummins and be amazed with the difference between AFE's fuel system vs other aftermarket brands. Four years of testing is what it takes to make a fuel system perfect, and AFE spent the time to make sure that they developed a system that has no rival. Instead of a lengthy and time consuming installation like other brands, the DFS780 installs in just a few hours for immediate use. The full time operation model bypasses your stock lift pump taking the reigns to keep your Cummins roaring with constant power.

It's easy to get caught up in the aftermarket excitement, especially with things that add an instant boost in awesomeness. A bigger-better suspension system, great injectors, roaring exhaust, an air guzzling cold-air intake; these all deliver kick in the pants power gains, and let's face it, are just plain fun. But it is important to remember that adding all these aftermarket parts require you to strike a balance with all aspects of your truck, and a very important aspect is fueling. In fact an upgraded fuel system becomes increasingly more important with each aftermarket item, failure to replace or improve your stock lift pump could leave you high and dry!

Enter AFE's DFS780 Fuel System, this powerful system does not require you to modify your fuel tank, instead it by passes your existing lift pump and works as your full time fuel system. As such, the DFS780 removes the remainder of the power-robbing entrained air, water, and contaminants directly stimulating the performance of your Cummins. You'll also notice improved throttle response as well as increased horse power and torque at all RPMs.

Unlike other brands, AFE designed the DFS780 as a single filter system; other brands use two filters, one for the fuel and another to separate water. Instead, AFE integrated clear water separation bowl attached to the high-efficiency fuel filter eliminating the need and expense of replacing two filters. The water separator bowl is reusable and can be emptied easily. AFE recommends changing the DFS780 fuel filter every 10 to 20 thousand miles.

While the DFS780 can definitely be equipped to a completely stock vehicle, you will notice the most gains with an assortment of aftermarket parts that require better fuel and better fueling. Each DFS780 unit is tested at AFE to ensure peak performance, the unit is flowed and rated at a minimum of 2.0gpm (gallons per minute), this rating can support over 2000HP.

Along with added horsepower the DFS780 will also increase the performance of your truck while towing. By proving enough fuel for even the toughest towing situations you'll notice almost no loss of power.

Replacing the fuel filter on your DFS780 is easy and can be replaced with either an AFE or Donaldson filter.

Perfect for my son with EXTREMELY sensitive skin
Size: Size 5 (132 Count), Size: Size 5 (132 Count)
My son has extremely sensitive skin, and most diapers cause hives or a rash. We’ve tried countless brands and had eventually settled on Bambo Nature, but their prices increased significantly, so I started looking for a more affordable alternative. Although the product listing doesn’t clearly mention it, these diapers are absolutely latex-free, and that’s a huge deal for little ones like ours. Amazon should really make that more obvious in this listing, since latex-free diapers are a necessity for my son. I also found in my research that there was 3rd party testing that found no detectable PFAs in these, but even bambo nature had some detected. The best part? He has had zero reaction to these. No hives, no rash, nothing. On top of that, they’re adorable, highly absorbent, and cost about half as much as the brand we were previously using. I genuinely wish I had tried them sooner. For this price, I wouldn’t even care if Amazon Prime ads were printed on them. I also love the stretch in the tabs and the back waistband area. It’s the perfect amount of flexibility for my very active toddler without feeling flimsy. We have had zero leaks, even overnight. My son actually keeps looking down at them before getting dressed, like he notices and approves of the fun prints compared to his old plain diapers. For the price, quality, and the fact that they actually work for sensitive skin, these have been an excellent find. This is all we will use from now on.

Great Diapers
Size: Size 5 (33 Count)
These diapers have been a lifesaver for our family. They fit really well without being too tight and my daughter is comfortable. I love that they don’t sag easily and the stretchy sides help prevent leaks while still allowing my child to move around freely. The absorbency is impressive, especially during naps, and we’ve never had a blowout. Another huge plus is the price. It’s hard to find diapers that work this well without spending a fortune, but these are a great value for the quality. They hold up just as well as more expensive brands, making them perfect for everyday use. I would definitely recommend them to parents looking for dependable diapers that fit well, absorb great, and are budget friendly.

Great bang for your buck
Size: Size 1 (50 Count), Size: Size 1 (50 Count)
Gotta say this is a pretty good diaper for the price! Not as soft as your luxury name brands but still very soft. Great absorption, no leaks, moisture stripe works. I like that they're mostly plain, I never understood why diapers needed to be "cute." The adhesion tabs work well, even though I did waste a diaper accidentally ripping one off. x) As for negatives this diaper is narrower than all the other brands. Which is fine, it still fits my baby but I probably won't be buying these again unless im using them as an in between from nb to size 1

Comparable to Major Name Brands in price and quality
Size: Newborn (30 Count)
Good value for the price , comparable in value and quality of major name brands. Visually attractive and detailed product description on packaging. Newborn size package is very small and well packaged for easy storage. Diapers are made to fit comfortably to newborns body and manufactured to wick moisture into the diaper away from babies skin and so not to leak. They absorb a fairly good amount of liquid with no problems. The adhesive tabs stick well and do not come lose.
