The AFE DFS780
Fuel System with Full-Time Operation for your 2003-2010 Dodge
5.9L/6.7L Cummins, 11-16 Ram 6.7L, 99-16 Ford Powerstroke, and
01-16 GM Duramax 6.6L 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
High-Impact Polycarbonate Sight Glass:
Allows visual inspection of fuel.
Bronze Spur Gears:
Bronze gears more forgiving of contaminants than steel gears.
The Helical spur gear design runs quieter than straight cut
6061-T6 Aluminum Manifold:
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.
& 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
The DFS780 is powered by your ignition and can be run independently
or in parallel with the stock fuel pump.
Bearing Wear Surfaces:
The DFS780 spur gears ride on PEEK (Polyether Ether Ketone)
bearing surfaces to reduce both noise and wear.
CNC Machining Of Manifold Passages:
Enhances flow through the manifold to reduce pressure drop
due to flow restrictions.
Bolt-on Steel Mounting Bracket:
Heavy duty bracket mounts to the frame and utilizes existing
hole to secure.
Pressure Gauge Port:
1/8" NPT port allows customer to attach an external
pressure gauge to monitor fuel pressure.
Quality Viton Seals:
Compatible with diesel and biodiesel fuels.
