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.

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.

Just ok
These are just simply too large to use as chapstick unless you do both top and bottom at the same time ( no thank you). I threw them away. 3 stars because it appears to be a good product, but they got the packaging all wrong to call it chap stick.

Replaced Vaseline - Far superior product
I received this as a gift a few months ago and it's all I use now. I use it on my lips and on my neck wrinkles.
Do not leave it in a warm environment, like hot car or pants pockets, it will get very soft. If it does get soft, i just dab it on ranther than rolling/wiping on.
Also its best to roll it down when not in use, but not necessary.
I used to be addicted to Vaseline products for my lips and this is far superior in many ways.

Not really good as a lip balm
It is way too melty or liquidy when applying. It's like putting oil on your lips. No staying power. I actually ended using it more as a skin moisturizer like a lotion. It's pretty good for that. I haven't even tried taking it with me in my pocket as I think it'll turn to a liquid like coconut oil down here in sunny hot Florida. .

Best lip balm I have ever used.
By far the best lip balm you will ever buy. When I say I am addicted to Chapstick/lip balm it's an understatement. I don't just have one kind, in one place. I have multiple kinds (you never know what you're feeling or need) in every place! Like my cars chapstick has a chapstick family. I have been trying to pay attention to ingredients lately and realize how many awful chemicals are in most of the products I use. So...here we are, woke up after sleeping with a fan in my face and my lip was dry and cracked straight down the middle. Something so stupid caused so much discomfort I started immediately trying all the different brands, oils, balms, etc. Some burned, some made it worse, some did nothing. Two days of this nonsense and I decided to try this product. It was delivered the next day thank goodness because I was becoming so annoyed with the pain from a small cut. I instantly put the product on and my lip felt so much better. It lasts a very long time so it isn't drying back out and it isn't painful to reapply when needed. It's been less than 24 hours and my lip is almost better. I even slept with the fan on. This balm is amazing, made in the USA, comes in a huge tube unlike the other brands, costs is amazingly low, and it has no nasty smell at all! The only complaint I have would be my concern for my addiction to carry one in my pocket and due to the ingredients it will probably melt some but I will worry about that when I need to. Seriously, this stuff is so amazing I had to write this review. I don't know these people and I sure didn't get it for free. I will be purchasing more from them and sharing what a quality product it is. Just get it.
