Ensure that your EcoDiesel is getting a steady supply of good, clean fuel no matter the engine load by upgrading with a DFS780 fuel pump. By operating full time, as opposed to AFE's Boost Activated model, you're ensured you always have fuel on tap for any performance level. Also, this system will ensure that you are getting the best possible fuel economy out of your already fuel efficient Ecodiesel!Helical Bronze Spur Gears:
- Bronze gears more forgiving of contaminants than steel gears. The Helical spur gear design runs quieter than straight cut gears.
- Eliminates porosity concerns with cast aluminum.
- Protected against dust intrusion and powerful water jets.
- Supplied harness attaches directly to battery and utilizes Deutsch weather-proof connectors. No cutting or modifications of the stock fuel lines required. Vehicle can easily be returned to stock.
- Supplied preset boost switch activates pump only under load, reducing wear tear on both the DFS780 and the stock lift pump.
- The DFS780 spur gears ride on PEEK (Polyether Ether Ketone) bearing surfaces to reduce both noise and wear.
- Enhances flow through the manifold to reduce pressure drop due to flow restrictions.
- Heavy duty bracket mounts to the frame and utilizes existing hole to secure.
- 1/8" NPT port allows customer to attach an external pressure gauge to monitor fuel pressure.
- Compatible with diesel and biodiesel fuels.

Works for foot psoraisis
Size: 2 pairs black L
Got these for work (service industry) to reduce issues with psoriasis and blisters while putting on 20k+ steps a day. Over time the wounds healed and I could work without so much pain. I now don't use them all the time like I used to, only when a new lesion or blister appears, too prevent a breakout. Tip: if you're not in full breakout, wear thick socks under these as a barrier to friction.

Work well but run small
Size: 1 pair black L
They do seem to run a bit small. I bought them for my bf but snagged them from him because I couldn’t resist! I’m about a W8/12 and they were just a little big but unlike others, I just put them on while sleeping and didn’t walk around with them. If you’re just planning on that, they did a great job at sloughing and moisturizing 😎

Good socks they work.
Size: 2 pairs black L
I normally wear size 13&half to 14 men's, and these fit me ok. They sit just below the ankle. They can get a little tight for me so you should look out for that if you are on the thicker side. But they work as advertised and help moisturize your feet. I recommend wearing them if you're going to just be hanging around home for a bit in one spot as they can be a little slippery to walk in if you go fast. Would not recommend going up and down stairs.

REALLY unsafe to walk around in these
Size: 2 pairs black L
They do what they are expected to do, but should only be used if you are stationary. The gel base makes for very unstable footing if walking around
