The AFE 42-14021 DFS780 Fuel System with Full-Time Operation for your 2011-2016 GM 6.6L Duramax LML offers you a complete fuel system solution for your Duramax pickup. The fuel in your truck contains contaminants, water and air/vapor which reduces power and can cause damage to your injectors.

Clear High-Impact Polycarbonate Sight Glass:
Allows visual inspection of fuel.
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.
"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.

perfect size
purchased for entertaining when I need convenience and quantity. good for larger gatherings- they look good, hold a lot of food without leaking. Strong enough to carry loaded with food without sagging, thick enough to cut meat and not cut through the plate. Can warm up food in microwave and not worry. After the party just toss in the garbage for easy clean up. I will continue to buy these plates.

Nice Platters for family Thanksgiving take out
The family used these to take some Thanksgiving food home. These paper platters are sturdy and hold food without bending or leaking. I like the size because it works well for bigger meals or when I don’t feel like washing dishes. They make serving and cleanup quick and simple.

Perfect for Thanksgiving and Christmas
These platters are sturdy and just the right size if you’re having a Thanksgiving or Christmas dinner and don’t want to deal with a bunch of dishes. My family use them for the first time this year and we were absolutely delighted. The platters are sturdy, high-quality, significantly larger than the 10 inch paper plates and hold a large amount of food which is essential when you’re serving a large meal.

Perfect for every occasion. Absolutely love this brand.
We always buy disposable tableware from Dixie, and these platters are another great product from the brand. The size is perfect for barbecue food, burgers, ribs, sides, everything fits easily. They’re sturdy, don’t bend or leak, and hold up well even with heavier food. We host BBQs often and these make serving and cleanup super easy. Reliable quality and definitely worth buying again.
