Grab the AFE DFS780 Fuel System with Full Time Operation for your 2003-204.5 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.

Did the trick!
Size: 11 Ounce (Pack of 1)
This has helped my 1 year old eczema so much! It’s nice and thick and if I put it on at night he is still really soft and smooth in the morning. I would recommend especially at this price!

Don’t rub, break it down between your fingers and dab!!
Style: 4 Fl Oz (Pack of 1)
Great sunscreen. The first time I applied it, i made the mistake of rubbing it in so it gave me a white cast. I learned my mistake the second time, spreading it in between my fingers and than dabbing it on my face, it gives a cast at first but after a few minutes it went away. And it feels so good. like I’m not wearing anything. I tried the tinted sunscreen it feels good but it made me look orange. I used to wear the Eucerin Daily Lotion spf 30 but they discontinued so I had to look for a replacement and after trying other sunscreens they were all terrible; greasy, allergic reactions and too creamy! This one’s perfect, it’s definitely my new go to!!

The Only SPF My Skin Will Tolerate!
Style: 4 Fl Oz (Pack of 1)
After 20 rounds of radiation, I was given a list of exactly four things I could put on my face--things like water and Vaseline. Of course, I was also instructed to wear SPF in "all visible light." However, finding a sunscreen my skin could tolerate proved to be a challenge, as even those made with clean ingredients, marketed for babies, and/ or claiming to be hypoallergenic resulted in hot, angry rashes. Price point also didn't matter; I tried everything from drugstore to premium brands. Thankfully, when this product came on the market, my dermatologist suggested I try it. I've been wearing it ever since. It IS thick so I usually rub any remaining face moisturizer into my palms and then add the Sunscreen, rubbing and warming it between my palms to make it more easily spreadable. Then I press it onto the skin on my face with my palms and fingers--I don't like to pull or tug too much at the skin on my face. At first, there is a visible white cast, but it disappears within a couple of minutes. If I'm really in a hurry, now I can mix a tiny bit of my foundation into the sunscreen so that it spreads faster and I can move on from the white cast faster--I know I lose some sun protection factor that way, but my derm says I also gain some protection in the tinting, so it's okay. The important thing is that I get it on in whatever time I have. I'm just grateful to have found something that doesn't upset my crazy-sensitive skin! Wishing all you sensitive beauties protected fun in the sun...

Good sun protection without chemicals, without a high price.
Style: 4 Fl Oz (Pack of 1)
I've bought this a couple of times. I feel like it gives excellent sun protection at a reasonable price. I mostly use it on my face. When I first apply it, it looks a little white and pasty, but it doesn't take long for that to go away. It's a little greasy at first , but I have dry skin, so I it absorbs in. I like using a sunscreen that doesn't have a lot of chemicals. This works well while using ingredients I feel good about putting on my skin.
