AFE Full Time Fuel System

Allows visual inspection of fuel. Bronze gears more forgiving of contaminants than steel gears. The Helical spur gear design runs quieter than straight cut gears. Eliminates porosity concerns with cast aluminum. Protected against dust intrusion and powerful water jets. 

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. 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. The DFS780 is powered by your ignition and can be run with the stock fuel pump. The DFS780 spur gears ride on PEEK (Polyether Ether Ketone) bearing surfaces to reduce both noise and wear. Enhances flow through the manifold to reduce pressure drop due to flow restrictions. Heavy duty bracket mounts to the frame and utilizes existing hole to secure. 1/8 NPT port allows customer to attach an external pressure gauge to monitor fuel pressure.
