Grab the AFE DFS780 Fuel System with Full Time Operation for your 2005-2010 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. Each are available as single units or as a 3 pack. Simply select the option above for additional filters or check out the related products!

Good for skin
Yes!!!! This actually works but the results are not permanent you have to continue using. But it does work for while in use. Would not recommend for the face though. Or should I say do not use often on face because it makes the face so oily. And not in a good way.

It works!
This is the only lotion I’ve been using on my body. I use koji acid Turmeric soap, and I use this lotion after. I’ve had these scars for years, and I’m definitely noticing a difference. I’m sure it’ll take months to finally get clear skin, but it does work. The lather could be better, so you do have to use a lot. I wish the bottle was bigger, especially since I use it on my entire body. So I have to use a lot. A bottle only last for about a month if your using it on large parts of your body. The smell isn’t bad at all, and it’s very lightweight. It doesn’t feel super moisturizing, but it’s good to SOLEY treat dark marks, but not your average everyday moisturizing lotion. But you can see a slight difference on my legs, and other parts have been clear very well. This is a great product, for a great price. I highly recommend pairing with a soap that treats dark spots.

Different package
I have been using this product for almost two years, and I absolutely love it, especially because I have very dry skin. It leaves my skin feeling extremely soft and well-moisturized even the next day. Over time, I also noticed that my dark spots started to fade. It is a great product, but it does take time to see results with dark spots. Yesterday, I ordered the same body lotion, but it arrived with a different packaging and formula. I was afraid it might affect the progress I’ve made with my skin, so I returned it and requested the original version I’ve been using.

Scent is off putting.
Seems to be a nice lotion but for me, the aroma is off putting. That makes it hard for me to use on a consistent basis. It is moisturizing and not greasy. It absorbs well into my skin. I wish it were fragrance free. My spots are still with me but that’s my fault.

Get the combo!
Mix these 2 together and thank me later. I wish i had done before and after pics but this combo lightened my knee caps, underarms and bikini area so fast! I haven’t used deodorant in 3 days because of the lotion! It’s that effective I’m about to order 4 more bottles
