The AFE 42-12021 DFS780 Fuel System with Full-Time Operation for your 2003-2004.5 Dodge 5.9L Diesel offers you a complete fuel system solution to replacing the factory lift pump in your Ram pickup. The fuel in your truck contains contaimants, 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.

Great fit
Size: 38DDD, Color: French Blue Lace
I first ordered this bra about 3 years ago. You know how us woman are we have more than one bra and more than one style of bra. This one style is the one I mostly reached out for. Then I went and lost around 45 pounds and it just didn't fit right any more. I went to to one of those "Bra Stores" and tried on a bunch of different bras none felt like it fit right so I came home and "measured" myself and I ordered a pretty blue one from comfort choice. My old bra was a 42G my new size is 38DDD. It fit so well I ordered 2 more. Light grey and pretty pink. I love these they are very comfortable and they hold the girls in place! Me I'm 67 5'3" and 165lbs.

Nice support but...
Size: 42DDD, Color: Black
I ordered this for my cousin who finds it very difficult to find bras in her size. She told me she wished she could find a good support bra without the wire because she had deep red marks under her old bra so I did some research and found this bra. She came over and tried it on and my first impression was WOW the support is great but it was very difficult for her to fasten all the hooks in the front due to her long nails. After some time she managed to fasten all the hooks and I noticed I needed to adjust the straps for her and she said it felt a lot better. This wireless bra looks so different on a woman with large breasts than the models in the picture, my cousin's cleavage was very substantial, unlike the model in the pic so if you are heavy set with large breasts, just know you will still have ample cleavage showing. After she put her top back on I noticed just how smooth her back looked, there were no bulges showing and she told me she felt like her posture was better due to the support of this bra. I have four stars due to the hooks being difficult to fasten.
