Grab the AFE DFS780 Fuel System with Boost Activation for your 6.6L Duramax 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.

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!

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 187 gph (gallons per hour), 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.

Nice so far.
Size: 6.5, Color: Molasses
Comfy. They were tight the first day across the toes but as I've worn them a couple times they are loosening up. The sole is forming to my foot. These are very much like Doc Martin's from the early 2000s. Not sure about quality since I haven't had them for very long.
