The AFE 42-14011 DFS780 Fuel System with Full-Time Operation for your 2001-2010 GM 6.6L Duramax offers you a complete fuel system solution to replacing the factory lift pump in your Duramax pickup. The fuel in your truck contains contaminants, water and air/vapor which reduces power and can cause damage to your injectors. The AFE DFS780 Fuel System features a patent-pending design capable of removing power-robbing entrained air, water and contaminants. The DFS780 ensures constant availability for your CP3 injection pump, while improving throttle response and horsepower at all RPMs.
Clear High-Impact Polycarbonate Sight Glass:
Allows visual inspection of fuel.

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.
"Marine Grade" Motor:
Protected against dust intrusion and powerful water jets.
Horsepower & Flow:
The DFS780 can be used on a totally stock truck, it was engineered for modified vehicles. BSFC (Brake Specific Fuel Consumption) for most modern turbocharged diesel engines is about 0.36 lbs/HP/hr. Since #2 diesel weighs about 7 pounds/gallon, which gives us about 19.5 HP/gallon/hr. The DFS780 will flow enough fuel (at rated pressure) to support over 2000 HP.
Plug & Play Installation:
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.
Relay Controlled:
The DFS780 is powered by your ignition and can be run independently or in parallel with the stock fuel pump.
PEEK Bearing Wear Surfaces:
The DFS780 spur gears ride on PEEK (Polyether Ether Ketone) bearing surfaces to reduce both noise and wear.
Contoured CNC Machining Of Manifold Passages:
Enhances flow through the manifold to reduce pressure drop due to flow restrictions.
Direct Bolt-on Steel Mounting Bracket:
Heavy duty bracket mounts to the frame and utilizes existing hole to secure.

They are very quality
Size: 11 Little Kid, Color: Gold, Size: 11 Little Kid, Color: Gold
My daughter loved the sandals. They look good on her feet. She has a narrow foot so they fit her just fine. I gave four stars because she wears a size 10 shoe now and I ordered an 11 thinking that she would be able to grow into them. As you can see from the pictures, they fit her perfectly. Everyone has one foot that is bigger than the other, so her bigger foot is hanging off the back. I purchased these for her summer sandals now I’ll have to buy her some more because these will not last through the summer.

Cute, sturdy, versatile
Size: 6 Big Kid, Color: Off-white Faux Leather
I bought several pairs of these to get the right sizes lol. I originally purchased for my 9 year old xoxo for a vacation but I got a too big, my 13 year old grabbed them tried them on and LOVED them. So, I ordered three more pair, found the right size for my 9 year old and sent the other two back. These are cute, versatile, sturdy, and GREAT price. I live that they buckle, are closed toes, but airy. Can dress up or down.
