Product Details

Product Name: DFS780 Fuel System Pump Kit
Manufacturer: aFe

The AFE DFS780 Fuel System with Full-Time Operation for your 2017-2019 GM Duramax offers you a complete fuel system solution to replacing the factory lift pump in your Cummins pickup. The fuel in your truck contains contaimants, water and air/vapor which reduces power and can cause damage to your injectors. The AFE DFS780 Fuel System features a patent-pending design capable of removing power-robbing entrained air, water and contaminants. The DFS780 ensures constant availability for your CP3 injection pump, while improving throttle response and horsepower at all RPMs.

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.

Horsepower and Flow:
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.

Plug and 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.

Relay Controlled:
The DFS780 is powered by your ignition and can be run independently or in parallel 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 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.

Make sure your diesel is prepared to perform in the coldest conditions with aFe's DFS780 Fuel System Cold Weather Kit.
