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.

  • Bypasses OE Fuel Pump (Full-Time Operation)

Super cute… but not what the listing is
Size: One Size, Color: Dark Cappuccino, Size: One Size, Color: Dark Cappuccino
First of all, this listing is entirely inaccurate, as other reviews say, the picture is of a larger bag when in reality you are sent something much smaller and without the small wallet. I wanted the smaller bag, so I ordered it intentionally, but if you are looking for the larger size, do not order this. I included a side by side comparison of the two bags. The lighter bag is the size this listing is supposed to be (that I owned previously) and the smaller one is the one I was sent. That being said the smaller bag is super cute and so similar to the Brooklyn bag! Just be aware that it does not match the listing :)

Size: One Size, Color: Dark Cappuccino, Size: One Size, Color: Dark Cappuccino
This purse has a good size for an every day purse. It’s a pretty style purse, and reminds me of the Coach brooklyn shoulder bag. I’m not too crazy about this bag since the material is thin and flimsy, but I should be okay.

Very cute bag, but not as described in picture. The bag I received is much smaller and does not come with additional coin purse. Disappointed.

Not the same bag
Size: One Size, Color: Dark Cappuccino, Size: One Size, Color: Dark Cappuccino
The item I received appears to be a smaller version of the bag without the small wallet that should be included. Do not buy it, and save yourself the trouble of having to return it.
