AFE 42-12034 DFS780 Fuel System (Boost Activated) 2011-12 6.7L (NO CA SALE)
2011-2012 RAM 6.7L CUMMINS (WORKS WITH FACTORY PUMP)
The AFE 42-12034 DFS780 Fuel System with Part-Time Operation for your 2011-2012 Dodge 6.7L Cummins provides you with a fuel system upgrade designed to work with the factory lift pump in your Cummins 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 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 & Flow:
The DFS780 can be used on stock or modified trucks. 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 & 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 you to attach an external pressure gauge to monitor fuel pressure.
O.E Quality Viton Seals:
Compatible with diesel and biodiesel fuels.
