*Built-in Bypass For Stock Fuel System:* Allows vehicle to run on stock fuel pump under light loads, reducing wear & tear on both the DFS780 and the stock high-pressure pump. *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 both the DFS780 and the stock lift 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.
