aFe Power DFS780 Fuel System (Boost Activated) | 2003-2007 6.0L Ford Powerstroke

The diesel fuel in your truck contains contaminants dirt, water and air/vapor which is reducing power and damaging your diesel fuel injectors. Introducing the aFe POWER DFS780 18-20 PSI Diesel Boost Activated Fuel System for the 2002-2007 6.0L Ford Powerstroke, with its patent-pending design capable of removing power-robbing debris such as air, water and other contaminants. The DFS780 also boosts fuel pressure ensuring constant availability for the high-pressure pump, improving throttle response and horsepower at all RPMs.

The DFS780 was designed from the beginning to eliminate weaknesses found in other "fuel transfer" system. aFe has spent almost four years engineering what we feel is the best, most reliable system available. Depending on the specific application, we offer features such as boost-activated fuel flow increase, a high-impact polycarbonate "sight glass" to visually check fuel conditions, a reliable "marine grade" motor and Viton seals to name a few.

Features

• Clear high-impact polycarbonate sight glass for visual inspection of fuel
• Helical spur gears runs quieter than straight cut gears
• "Marine Grade" motor protects against dust and water
• Output pressure of 18-20 psi
• Contoured CNC manifold enhances flow
• Fuel pressure gauge port
• O.E. quality Viton Seals
• Typical install is 2 hours
• Built in the U.S.A.

Built-in Bypass For Stock Fuel System
Allows vehicle to run on stock fuel pump under light loads.

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.

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.

Boost Activated Pump Engagement
Supplied preset boost switch activates pump only under load, reducing wear & tear on the DFS780 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 Viton Seals
Compatible with diesel and biodiesel fuels.

Note
This system is not currently CARB exempt and is not available for sale in California or for use on any vehicle registered with the California Department of Motor Vehicle.
