Grab the AFE DFS780 Fuel System with Full Time Operation for your 2003-204.5 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.

Good shelf to upgrade my awkward kitchen!
Size: 42 inch 2 Tier
This shelf is exactly what I was looking for for my awkward kitchen in my new house. Don't mind the plywood walls (who knows what the previous owners were thinking 🤣) but anyways, we had this awkward gap between the kitchen counters and the stove, so I got a stainless steel shelf to fill the gap and add some more counterspace, and I found this industrial style pipe shelving, which was the perfect size and height to fit in this gap on the wall and give us more storage/organization space. It's easy to assemble and hang up, and seems very strong and sturdy. It's a little heavy, but lightweight enough to hang easily. Right out of the box, it was disappointing to see some scuffs in the black paint on the piping, especially for the price. Luckily, the biggest scuff is in a pretty inconspicuous space so it's not a big deal. Definitely not worth returning to see if another one wouldn't have any scuffs (especially since many of the other reviews mentioned scuffs too). It's wabi sabi I suppose 😅 Also, not a single extra screw or hardware was included. Not a big deal, but screws are cheap enough to through in one extra just in case one is missing or lost. Overall, mostly happy with the purchase. The wood is solid and the shelf looks nice in my kicthen!

Easy to put together. A little bit too heavy for Sheetrock. I had to use some bigger screws. I love the look with my cabinet.
