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.

This is the best dental product on the market!
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1), Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
I rarely take the time to review so if I do I think that it's because it's something people need to hear. I have and have had many animals. For years I have been trying to find a way to brush our dog's teeth beyond minties, because while those are great it's not enough. I've bought over ten different products that have ended up in the trash. I gave up, but we recently added two new puppies. Our current dog line up after our senior passed is a 1 year old Shiba female, a 12 week old Japanese American Akita, and an 11 week sable Pomeranian. As I've done more research Poms especially are prone to dental issues so regular complete dental care is important. So I went back to the sea of products.. I ended up getting hicc silicone finger scrubs and a toothpaste that they all gagged at. So another toothpaste thrown away.. I decided to keep the fingers Incase I could find something else. Chatgpt actually recommended this specific toothpaste, I figured I'd try it even though I didn't have high hopes. Infact it actually sat in my petcare box for a bit because of that. Today I finally tried it and it's Amazing, not one, but all three very finicky opinionated babies love it! Like obsessed. I mean not just picking but actually chewing and letting my brush their teeth, each didn't wanna stop. I am so impressed. Not only am I taking care of their dental hygiene but it's an enjoyable treat to them. The tube is huge(human toothpaste size), I can tell it'll last us a very long time. It's affordable. It doesn't stink either. I purchased the poultry one I believe because I thought it was a good place to start and it was an instant hit. So save yourself the headache and wasting money on different pastes and brushes. Get hicc finger brushes and one of these and I promise you'll never have to fight to take care of your babies teeth again. Plus, no stinky breath and the product it's self doesn't stink. I would legitimately say this is in my top 5 of best purchases this year. Hope this helps someone out there struggling like I was(:

The “Please Brush Your Cat’s Teeth Without Losing a Finger” Solution
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
Let’s be real—brushing a cat’s teeth sounds like something you agree to before you fully understand what you’ve signed up for. This toothpaste is basically here to make that whole situation slightly less chaotic. The first thing that makes this stand out compared to a lot of other pet toothpastes is that it’s enzymatic, meaning it doesn’t just “scrub” teeth—it helps break down plaque using a dual-enzyme system that works with your pet’s saliva. That’s why vets recommend it so often: it’s doing actual chemistry in your cat’s mouth instead of just pretending to clean things with minty hope. Another big win is the poultry flavor. And yes, that sounds weird for humans, but for cats and dogs it’s basically “treat mode unlocked.” A lot of pet toothpastes fail immediately because animals take one sniff and decide dental hygiene is a personal insult. This one is actually accepted by many pets, which makes brushing less of a wrestling match and more of a “bribe situation.” What also makes it better than cheaper or generic options is what it doesn’t have—there are no foaming agents and no harsh ingredients, so it’s safe if your pet swallows it (which, let’s be honest, most of them will). That alone saves you from the panic of “did my cat just eat toothpaste??” every time. Now, the honest part: this is not magic. If you think you’re going to squeeze this onto a toothbrush once a week and end up with Hollywood-white cat teeth, no. It works best when used consistently, ideally with some actual brushing, not just letting your cat lick it off your finger like it’s dessert (although, yes, many cats will try exactly that). Also, some cats still act like you’re personally ruining their life the moment a toothbrush appears. This product does not fix cat personality disorders. It just makes the process less miserable. Where it really shines is that it sits in this sweet spot between “vet-level serious” and “actually usable at home.” Cheaper toothpaste often feels like flavored gel with optimism. This one feels like it was made by people who have actually tried brushing a cat that doesn’t respect authority. Compared to similar products, it wins on three things: real enzymatic action, high pet acceptance rate, and vet-backed credibility. It’s not the cheapest, but it’s one of the few where you feel like your effort is actually doing something instead of just negotiating with a tiny furry dictator. No toothpaste on earth can fully solve the “my cat refuses cooperation on principle” problem. But in everything it can control? This is one of the best options out there.

This stuff is amazing!
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
This stuff is the best I’ve found over all other pastes, powders, and chews. My standard doodle had some nasty plaque buildup on his back molars. I tried everything to clean them up but nothing seemed to work. After reading about this stuff I decided to give it a try. I use it once a day with a finger cot. I’m just about done with the first tube and the results are amazing! The plaque is almost entirely gone and he loves the taste of this stuff. Just ordered my second tube. Very happy!!!!

Already seeing a difference after a few uses!
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
Started using this on our dog after noticing significant build up and have seen an almost immediate difference with semi frequent brushing! Seems pretty effective and is easy to use. Our dog seems to like the scent/flavor as well.

Cat loves it
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
I don't know how well it cleans yet, as we haven't gone back to the vet, but my cat loves the flavor. My cats breath has improved, easy to use because he loves it.
