The AFE 42-13051 DFS780 Fuel System With Full-Time Operation for your 2017-2019 Ford 6.7L Powerstroke offers you a complete fuel system solution for your Super Duty 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 to your 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:

Beautiful but hurts
Size: 8.5, Color: Black-pu
True to size
Quality was great
I wore them for a wedding but the plastic strap made my feet hurt after a while
These are really a show stopper! Had plenty of people ask me where I bought them from
But be ready to apply bandaids

Adorable! 🥰
Size: 7.5, Color: Champagne-pu, Size: 7.5, Color: Champagne-pu
Can be a little uncomfortable if you’re a wide foot girly but overall comfy. A little slippery after lotion and some heat (I live in the muggy south), I’d possibly size down. Once you break them in they’re a little loose, at least for me. I usually wear a 6.5-7 I got a 7.5 to accommodate for the width. I could’ve done with just a 7.

Love these sparkly beauties!
Size: 9, Color: Silver-pu
Ahhh!! So pretty! Very comfortable as they aren't too high. They are super sparkly, especially in the sunlight! Received tons of compliments! I can't wait to wear them again!

My favorite
Size: 11, Color: Gold-pat, Size: 11, Color: Gold-pat
I'm absolutely in love with these heels! They are even more beautiful in person-the rhinestone bow adds the perfect touch of sparkle and elegance. The fit is comfortable, and the ankle strap keeps them secure while walking. The heel height is just right, giving a classy look without hurting my feet. Perfect for weddings, parties, or any special occasion. I received so many compliments-highly recommend!

Simple and sexy
Size: 8.5, Color: White/Pat
I love the shoes. They were true to size, and no hang over in the front. I did a lot of walking with these shoes. Very comfortable throughout the night.
