42-14012 aFe Fuel Lift Pump Diesel


Fuel Lift Pump Diesel; DFS780; OE Replacement; Boost Activated; 2 Gallons Per Minute; 8 To 10 PSI
Attributes Flow Rate: 2 Gallon Per Minute Pressure Rating: 8 To 10 Pounds Per Square Inch Inlet Quantity: Single Inlet Size: OEM Inlet Attachment: Hose Barb Outlet Quantity: Single Outlet Size: OEM Outlet Attachment: Hose Barb Includes Mounting Kit: Yes Introducing the aFe POWER DFS780 Diesel Fuel System, 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. Built-in Bypass For Stock Fuel System allows vehicle to bypass the DFS780 pump under light loads, reducing wear and 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. 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 is protected against dust intrusion and powerful water jets. 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. Supplied preset boost switch activates pump only under load, reducing wear and tear on the DFS780. 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. 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. O.E Quality Viton Seals are compatible with diesel and biodiesel fuels.
