aFe® - DFS780 Series Full-Time Diesel Fuel System

DFS780 Series Full-Time Diesel Fuel System by aFe®. The diesel fuel in your truck contains contaminants, water and air/vapor which is reducing power and damaging your diesel fuel injectors. Introducing the aFe POWER DFS780 Diesel Fuel System, with its patent-pending design capable of removing power-robbing entrained air, water and contaminants. The DFS780 also boosts fuel pressure ensuring constant availability for the high-pressure transfer 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 they feel is the best, most reliable system available. Depending on the specific application, they 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

• Built-in Bypass For Stock Fuel System: Allows vehicle to bypass the DFS780 pump under light loads, reducing wear & tear on the DFS780. Also allows engine to run even if the DFS780 unit were to fail
• 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
• 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

aFe® (Advanced Flow Engineering, Inc.) manufactures performance products for late model cars, light trucks and SUVs.
