AFE 42-13011 DFS780 Fuel System (Full-Time Operation)

The AFE 42-13011 DFS780 Fuel System with Full-Time Operation for your 1999-2003 Ford 7.3L Powerstroke offers you a complete fuel system solution for the fuel system in your Powerstroke pickup. The fuel in your truck contains contaminants, 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 fuel availability for your engine, while improving throttle response and horsepower at all RPMs.

Allows visual inspection of fuel.

Bronze gears more forgiving of contaminants than steel gears. The Helical spur gear design runs quieter than straight cut gears.

Eliminates porosity concerns with cast aluminum.

Protected against dust intrusion and powerful water jets.

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.

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.

The DFS780 is powered by your ignition and can be run independently or in parallel with the stock fuel pump.

The DFS780 spur gears ride on PEEK (Polyether Ether Ketone) bearing surfaces to reduce both noise and wear.

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.

Compatible with diesel and biodiesel fuels.
