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 material, stitching. Fit was unorthodox.
Size: Small, Color: Light Grey (Stretch Fabric)
putting on the suit for the first time, pants first, I thought that I had gotten a steal of a deal! The fabric was of good quality, had a good amount of stretch and was just long enough for my long legs. (typically wear a 32/34, but cuff the jeans once). It was the top section that I had an issue with. The shape of the shoulder-to-neck area was very pointed. As someone that has almost no trap muscle, this meant extra fabric that sagged on the my shoulders and gave me an unkempt look and I'm not sure this is something that a tailor can fix easily. If you have a little more beef up top, this would probably work for you. I wish it would have fit differently because I was impressed by the quality.

Do not waste your time
Size: 3X-Large, Color: Black
Wow! Lol extremely disappointed. I ordered this suit based off of the size chart and my accurate measurements. It was EXTREMELY small. So small that I could barely get my forearm through one sleeve. Not even close to my measurements. And to top it off, it was delivered in a clear bag, exposing the contents to the carrier and possible package thieves. So unprofessional.

Affordable, Stylish, and Fast Shipping!
Size: X-Small, Color: Black
I was hesitant to order this suit for my son’s homecoming, but wow! The quality is outstanding, it fit perfectly with no alterations, and honestly looked better than an overpriced fitted suit. He received tons of compliments, and I’ll be ordering more soon. Plus, it arrived the very next day. Highly recommend!
