Grab the AFE DFS780 Fuel System with Part 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 part time operation model works in conjunction with your stock lift pump taking the reigns in high boost situations 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 uses your existing lift pump and fuel filter system as an extra line of defense against contaminants common in diesel fuel. 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.

PEEK Bearing Wear Surfaces:
The DFS780 spur gears ride on PEEK (Polyether Ether Ketone) bearing surfaces to reduce both noise and wear.

Contoured CNC Machining Of Manifold Passages:
Enhances flow through the manifold to reduce pressure drop due to flow restrictions.

Direct Bolt-on Steel Mounting Bracket:
Heavy duty bracket mounts to the frame and utilizes existing hole to secure.

Great Shelves! Drywall Anchors are the Bomb!
These shelves are very plain as I hoped they would be so as to not take away from the items displayed. The blue is true to the images so I was impressed by that. Word of knowledge: if you do not hit any studs, don’t use the mollies that came with them; use plastic drywall anchors! They work amazingly well!

Pretty shelves for small space
Size: 17 Inch, Color: Natural
Good quality shelves and easy to install once I used my own stronger anchors and screws. The ones provided were too weak and made the shelf unstable. I had to patch several holes in my wall before installing them correctly. If they had provided better quality anchors I would have rated it 5 stars. Still very happy with my purchase.

Flimsy and doesn’t hold weight
Size: 17 Inch, Color: Natural, Size: 17 Inch, Color: Natural
Do not buy this. The frame this comes with is so small and flimsy. I didn’t even have anything on the shelves yet and they were falling off the wall. The wood is a beautiful color but the quality is awful. I had different floating shelves on the same wall and I included a picture of the thick metal frame those came with, also from Amazon to show how flimsy this brand is.

Really nice shelves well-made
Size: 30 Inch, Color: Walnut, Size: 30 Inch, Color: Walnut
I recently installed a set of floating wooden shelves above my kitchen sink, and they have completely transformed the space. The natural wood grain adds warmth and character, making my kitchen feel more open and inviting. The shelves are sturdy and well-made, supporting everything from dishware to small plants and decorative items without any sagging. Installation was straightforward, with the included hardware making it easy to mount them securely. I was pleasantly surprised by how well they hold weight while maintaining a sleek, minimalistic look. The floating design gives a clean, uncluttered aesthetic, which is exactly what I was looking for. Functionally, they’ve made a huge difference. I can now keep everyday essentials like mugs and spices within easy reach while freeing up valuable counter space. They’re also a great alternative to upper cabinets, preventing the area above my sink from feeling closed in. Overall, these floating wooden shelves are both practical and stylish. Whether you’re looking to add storage or just enhance your kitchen’s design, they’re a fantastic option. I highly recommend them for anyone wanting a simple yet impactful upgrade to their space!

Look nice, not sturdy or supportive
Size: 17 Inch, Color: Dark Blue
The color and thickness of the shelf is great. Very easy to install. But the wall mount portion is cheaply made and doesn’t support the shelf as well as it should. Once mounted the shelf leans forward and isn’t sturdy. After mounting, I found my items had slid off end up on the floor.
