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.

I (still) like it
Color: B Black
Looks solid, considering it is lightweight plastic. Very large. I have a large wrist and still I needed to remove 3 links. Link removal took a while to figure out. Needed the video (QR code in box), a bright light and magnifying glasses (to see the inside arrows and tiny pins). It seems to keep good time, though the hands are slightly off -- for example, at 3 o'clock, the hour hand is a bit after 3, not right on 3. At 6:15, it seems it will be 7 very soon. Maybe it will make me early for a change LOL. Mostly I just really need a watch to tell the time, without having to pull out my phone. This does the job, with a bit of style and a touch of irony. Update, after 5 months of daily use: The watch still looks good and the timepiece still functions. Sadly, a small piece of plastic broke off the watch band, where the pin connects, so the band will not stay together. It is a larger piece of the band, near the dial, so there are not extra links of that size to repair it. There does not appear to be a warranty. Up to this point, I have received several compliments on the watch. I agree that the contrast is rather eye-catching. I may buy a second one and use the first watch for parts.

Cheap dial
Color: E Gold Black
As a whole it's a quartz plastic watch for under $20...I'm disappointed in the poor looking dial quality. The case seems fine for a plastic watch, it's no Swatch but not a bad case. Shame the dial looks so cheap, it may have passed at a glance as a nice watch otherwise.

NOT WORTH IT
Color: E All Black
Not worth the money in my opinion. Very light weight. Almost like wearing a child's watch. Cheaply made.
