Clear High-Impact Polycarbonate Sight Glass:
Allows visual inspection of fuel

Helical Bronze Spur Gears:
Bronze gears are 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 the battery and utilizes Deutsch weather-proof connectors. No cutting or modifications of the stock fuel lines required. Vehicle can easily be returned to stock.

Relay Controlled:
The DFS780 is powered by your ignition and can be run independently or in conjunction with the stock fuel 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 the existing hole to secure

Fuel Pressure Gauge Port:
1/8″ NPT port allows customers to attach an external pressure gauge to monitor fuel pressure
