Grab the AFE DFS780 Fuel System with Full 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 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.

The best shoe brand I have found for toddlers! Exceptional quality
Size: 12 Little Kid, Color: Black/Beige
I have ordered a handful of shoes from Mini Melissa in the past, so I knew to size up. I typically order 1 to 3 sizes larger than what my daughter currently wears depending on the season and type of shoe. For this shoe, I ordered about 3 sizes up, so that she will be able to wear them next spring / summer and I am glad I did. They are a little large on her now, but I know we will get a lot of use out of them next summer playing in the yard, pool and beach! As with all Mini Melissa shoes, the first thing I do when I open the box is smell them - their shoes have the most pleasant scent! They make the best jelly-like quality shoes; they are absolutely worth the price for the quality and style you receive. They hold up very well - they are the only shoes that she outgrows before the shoe breaks down or looks unwearable. My daughter has worn many of their styles, and has never gotten a blister or complained about the comfort. They are supportive, but flexible and even as young as she is, she gets so excited for cute shoes! I ordered the beige and black for something neutral we can wear with many different outfits and that won't show dirt on the sole. The color is exactly as pictured. I really appreciate that top straps are functional and adjustable. She has a bit of a wider foot, so this allows us to get even more use out of them. I am very glad I ordered these and will continue to tell my friends about what I find to be the best shoe brand for toddlers and kids!
