Description

The AFE 42-12033 DFS780 Fuel System with Full-Time Operation for your 2011-2012 Dodge 6.7L Diesel offers you a complete fuel system solution to replacing the factory lift pump in your Dodge Ram 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 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 & 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 Seals:
Compatible with diesel and biodiesel fuels.

Features: 
  • Bypasses OE Fuel Pump (Full-Time Operation)
  • "Worry Free" 2 Year Warranty
  • Built In The U.S.A

Hard to give 5 stars

I'm going with 3 stars because.. When I changed out the old lift pump to the new one, I found that the fuel filter is Extremely small! I would say that the filter belong in a diesel golf cart, not in a Cummins 2500 6.7. The filter was completely clogged, and Thank God it didn't damage anything up to that point. Now, the lift pump... I've gone through a handful of tanks and I've seen very little gain in MPG to where it's hardly noticeable. Since I've installed this on my 2012 Ram 6.7, I've had a MUCH harder time starting the truck! It takes roughly 4-7 seconds just to start. So now I have to worry about a starter going out quicker than I would have liked. I have talked with the company, and they have 0 clue on what's going on, and was 0 help. Honestly, if I knew what I was getting myself into, I wouldn't have even bought this. I'm not sure if when it was "inspected" it was really inspected to AEF specs, or if I just have a bad lift pump. Be very careful buying this, you'll spend more money than just buying and installing!
