Grab the AFE DFS780 Fuel System with Full Time Operation for your 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.

DON'T SLEEP ON THESE DIAPERS! (but your baby should)
Size: Size 3 (40 Count)
I was skeptical at first trying out the plush version of this diaper because I thought the mama bear gentle touch was just OK and you can find a better diaper for the same price point. I saw these on prime day for the same price as the gentle touch and said why not. I was very, very impressed. They are soft and flexible with a satin-like exterior; similar to the feel of a hello bello diaper. The plush version definitely feels more quality than the papery gentle touch ones. I first tested the absorbency using 12 oz of water, waited ten minutes and dabbed dabbed dabbed. Seriously NO moisture! In comparison to the gentle touch diaper that had obvious moisture after the same test. I put them to use on my baby, who just for reference is 19lbs, for an overnight and the diaper did not leak and was only damp in the morning, not wet! Amazing. She is a moderate wetter but I still think that performance is great because in comparison to gentle touch, the diaper was wet on the inside after only three hours and I had to consistently use diaper cream so rash wouldn't develop; I would have never used the gentle touch as an overnight diaper. Seriously, for .21 a diaper for size three these diapers are a steal. DONT SLEEP ON THIS DEAL, PICK UP SOME MAMA BEAR PLUSH DIAPERS!

Not the Same 🤍
Size: Size 2 (184 Count)
I loved the Mama Bear size 1 diapers, so I expected the “plush” size 2s to be the same. Unfortunately, they feel completely different. These seem thinner and not quite as absorbent as the size 1 regular pack. The design is also really busy, which makes the wetness indicator harder to see at a quick glance. With babies, that little line matters more than you’d think. I’ll still finish the pack, but I’m not sure I’d repurchase this “plush” version. If you’re choosing between them, I’d recommend sticking with the regular pack instead. In comparison, Huggies still perform better than these for us. 🤍✨ They don’t hold blowouts at all but they do fit well. They’re also not stretchy. I noticed the print on my baby’s legs.

Great cost efficient option
Size: Size 4 (36 Count)
I switched over from Millie Moon and really like these. They’re affordable, don’t have harmful additives, and are soft and gentle on my babies. Holds a significant amount and doesn’t leak even on overnight wears. I like the simple non character design as well.

Every other diaper leaked
Size: Size 7 (92 Count)
I bought these diapers because they were the cheapest available to buy with a gift card my family was given. Normally I use the bulk store brands. The diapers were very hit and miss. It varies from diaper to diaper even in a pack. My son does urinate heavily but even before he would get anywhere near a “full” diaper it would leak! Leading to wet pants and messes. We’ve never had this problem with other diaper brands. Even our cloth diapers hold better than half of these did. For note he falls below the max size for these diapers by at least 5 lbs. I don’t plan on repurchasing these because of the leaking issue. Beyond that they were easy to use like any other diaper, didn’t cause diaper rash, held together, but was subpar in absorption.
