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.
Helical Bronze Spur Gears:
Bronze gears more forgiving of contaminants than steel gears. The Helical spur gear design runs quieter than straight cut gears.
Billet 6061-T6 Aluminum Manifold:
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.
Fuel Pressure Gauge Port:
1/8 NPT port allows customer to attach an external pressure gauge to monitor fuel pressure.
O.E Quality Seals:
Compatible with diesel and biodiesel fuels.

Not only is this THE best face, hand, & body cream, it's incredibly inexpensive!
This cream is a miracle! I found using a small amount (pea-sized, max) on my face and it's lovely! Within a few minutes, my face is soft, smooth, neither sticky or greasy, nor is it dry. I LOVE it! It's also great on my hands (again, only a tiny bit--less than the "pea-sized" amount that I had I applied to my face.) If you find that your face feels greasy in a few minutes, that means you put too much on. It spreads well and easily, but keep it to a small amount. And for the price (approx. $5 per big tube!) it's the best bargain around! I even apply it around my eyes (not too close to the lash line; you don't want to get any IN your eyes.) Just the tender skin around outside your eyes, and that never stings or burns--this cream never hurts me anywhere I apply it.

Smooth and Soothing
Much nicer than you'd expect from the description (Beef tallow). This white, skin-friendly moisturizing cream is odorless and not greasy. It feels good on the skin and sinks in readily. I plan to buy this again.
