The AFE 42-12031 DFS780 Fuel System with Full-Time Operation for your 2005-2010 Dodge 5.9L/6.7L Diesel offers you a complete fuel system solution to replacing the factory lift pump in your Dodge 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.

Features:
  • Bypasses OE Fuel Pump (Full-Time Operation)

They aren't super firm; they are more comfortable than rigid 😊
Color: White, Size: King Size Set of 2
I bought these pillows, and honestly, I really liked them. They have a medium firmness that helps significantly with neck pain, yet they remain soft and fluffy without going flat during the night. They hold their shape well and have good loft, so you don't have to keep adjusting them constantly. They don't have any unpleasant odor right out of the package, nor do they slide around much inside the pillowcase something I really appreciate. Overall, they feel comfortable and are of good quality for sleeping in any position.

100% Cotton Pillows .
Color: White, Size: Queen Size Set of 2, Color: White, Size: Queen Size Set of 2
These pillows feel soft and fluffy without being too flat. They provide nice support for the neck and feel comfortable whether sleeping on your side or back. After several nights of use, they still keep their shape well and don’t feel too warm during the night. The set comes with two pillows, which makes it really practical for the bed.

Luxury Comfort and Perfect Support – Best Pillows Ever!
Color: White, Size: King Size Set of 2
I recently purchased the Serta Hotel collection Pillows White Goose Feather Down Fiber Gusseted, and I couldn’t be happier with my choice! These pillows are the perfect balance of softness and support — plush enough to feel luxurious, yet firm enough to keep my neck properly aligned all night. The gusseted edges really make a difference, helping the pillow hold its shape and look full even after weeks of use. The quality of the materials is excellent — the outer cover feels smooth and breathable, and there’s no feather poking out like with cheaper options. I also appreciate that they fluff back up easily after use, making the bed look hotel-perfect every morning. If you’re looking for comfortable, high-quality pillows that provide great value for the price, I highly recommend these. They’ve truly improved my sleep!

Good quality pillows
Color: White, Size: Queen Size Set of 2
These are very soft and supportive as advertised. W find them a little too thick for my taste (why I only gave 4 stars), but personal preference is very subjective with pillows. They are well made and high quality, and am happy with my purchase.
