AirDog® II-4G Fuel Air Separation System featuring Demand Flow Technology and Enhanced Features

AirDog® II-4G is designed to operate at flows and pressures beyond the maximum requirements of the engine. It receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of water.

The fuel passes through the water separator which removes the large particulate contaminates that could damage or jam the gear rotor fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining enters the fuel pump.

The fuel, now under positive pressure flow, enters the fuel filter. As the fuel passes through the filter media and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated. Through the positive fuel air separation features of the patented AirDog® II-4G the separated air/vapor is discharged from the filter and back to the fuel tank through the Primary Air/Vapor Discharge Port.

The fuel passing through the filter media is now free of contaminates and power robbing air/vapor. At pressures and flows able to meet the needs of the engine, it exits the fuel filter through two passageways. First, the fuel for the engine passes into the fuel pickup tube and on to the engine. Then, the excess fuel not needed by the engine recycles internally through the pressure regulator back to the water separator.

AirDog® 
- The Original Fuel/Air Separation System
The Original Fuel Air Separation System

The AirDog® Fuel Preporator®, with the capability to provide fuel at flows and pressures beyond the maximum requirements of the engine, receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of moisture. The fuel passes through the water separator which removes the water and large particulate contaminates that could damage or jam the gearator fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining, enters the fuel pump.

The fuel, now under positive pressure flow, enters the filter. As the fuel passes through the filter media and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated. Through the positive fuel air separation features of the patented Fuel Preporator® the separated air/vapor is discharged from the filter through the Primary Air/Vapor Discharge Port and into the return to tank passage after the regulator. The fuel passing through the filter media (free of contaminates & power robbing air/vapor and at pressures and flows to meet the needs of the engine exits the fuel filter through two passageways. The fuel for the engine, passes into the fuel pickup tube and out to the engine).

The excess fuel not needed by the engine is released through the pressure regulator to combine with the air/vapor and foam as it returns to the fuel tank. The regulator controls the fuel pressure to the engine.

AirDog® Benefits

The AirDog® Fuel Preporator® removes various contaminates, including entrained air/vapor, particulates and moisture, and removes excess fuel not needed by engines, allowing the fuel to flow through the regulator and return to the fuel tank. The separated air/vapor enters the return port after the regulator, allowing pure fuel to flow to the engine at a regulated positive pressure. A gerotor pump offers quiet, long lasting performance. Some benefits include:

  • Removes Air and Vapor from Diesel Fuel
  • Pure Diesel Fuel Reaching Engine
  • High Flow Rates of Fuel to Engine
  • Longer Injector Life
  • Increased Injection Pump Life
  • Increased Fuel Economy
  • Optimized Engine Performance
  • Increased Torque Output
  • Improves Throttle Response

Duramax Diesel

The Duramax is probably the most responsive to an aftermarket lift pump. The GMC and Chevy Duramax pick-up trucks do NOT have a lift pump to supply fuel to the engine. From the factory, the CP3 injection pump is the truck's only means of getting fuel from the tank to the engine. If you were to look at our video of “How the AirDog works” it will show you what happens when the CP3 pump pulls fuel from the tank to the engine. Therefore because the fuel is under constant suction it causes cavitation and excessive wear and tear on injectors and your injection pump. Also, this is the #1 cause of low rail pressure codes when adding aftermarket programmers or tuners that increase the demand for fuel. By providing both constant positive fuel pressure and 100% pure fuel to the engine, is where you get the added benefits of smoother and quieter idle, better throttle response, increased fuel economy, better mid-range through top end power and more consistent rail pressure to support both stock and modified engines.

Because we have a few different systems for the Duramax, install difficulty and times will vary. For example; The AirDog II, FP100 and Raptor pump kits do not require you to drop the tank to install the system. Because of our OEM style quick connect fittings and internal pump design on the AirDog II, you will simply hook the suction line to the factory fitting on the fuel tank sending unit. However, if you're going to install an AirDog FP150, this will require dropping the tank to install a 1/2″ suction tube. None of the Raptor kits require a suction tube to be installed.

As for the rest of the install, for fuel supply, all of the systems will either hook to the factory steel feed line that runs up to the engine or the line directly on the engine, we give the choice of hooking to either spot based on your mechanical capabilities. On the AirDog and AirDog II systems, the entrained air and un-used fuel will be sent from the system back to the tank through the fuel filler tube. Also, the factory fuel filter housing will remain in use when using any of the AirDog or Raptor fuel systems.

Many people ask why the AirDog II, with its higher flow rate doesn't need the 1/2″ suction tube. The reason for that is the way the AirDog II is designed internally. The AirDog II recycles fuel back through the base to keep the system constantly full, therefore returning less and making it a true “ON Demand” system. Also, all of the AirDog and AirDog II systems have a built in pressure port on the top of the base directly above the fuel filter, it's plugged with an 1/8″ pipe plug and can be removed and utilized to check pressure from.

Dodge Cummins

Arguably the most widely known name in the diesel industry is Cummins. With their pick-up truck engine debut dating back to 1989, they have come quite a long way in perfecting one of the longest lasting engines on the market. Unfortunately, they are also known for having some of the industry’s worst lift pumps.

Starting back in 1989 through 1998, Cummins used a block mounted, cam driven lift pump. These were quite reliable; however, they were just the opposite when it came to priming the system. These pumps were designed to put out 25-30 psi of fuel pressure as well.

From 1998.5-2002, the lift pumps were still on the side of the engine, unfortunately they went away from the cam driven design and decided to go with an electric Carter pump. These pumps primed the system very easily; however they proved to not hold up to the violent vibrations and tortures that the engine put out, thus causing the temperamental VP44 injection pump that it fed to fail prematurely. These pumps were set to put out 12-14 psi to the VP44 injection pump to keep it cool.

From 2003-2004.5 Dodge decided to get away from the engine mounted pump and relocate it to the inlet side of the fuel filter housing. This small black cylindrical pump proved to be a little better than the block mounted version of previous years however they too had their problems. These pumps were set to put out 14-17 psi.

Starting mid-year of 2004, Dodge had a revelation and decided that it would be best to mount the pump in the fuel tank. This not only made it much more difficult to change should there be a problem but it also made it very expensive. While switching to this new design they also discontinued any out-of-tank lift pump replacements. This meant that should your block mounted lift pump go out on your 2001 truck, you would be “updated” to an in-tank pump design. These pumps were also set to put out 14-17 psi.

When it comes time to install of any of these kits, it’s imperative to know that should the truck have an in-tank fuel pump, it will need to be disabled and bypassed. The in-tank pump is not designed to be pulled through. It will cause excessive pressure on the AirDog or Raptor and could cause it to malfunction.

When it’s time to pull fuel from the tank, there are three ways this is done. The first would be to just hook right to the stock sending unit suction fitting. This is done on all trucks that do not have an in-tank lift pump.

Ford Powerstroke

Thanks to Ford there are many different versions and configurations of the Powerstroke engine. There's the tried and true 7.3 liter that ran from 1994-97 then changing a bit in the 1999-03 model years, the 6.0 that went from 2003-07, the 6.4 whose short life ran from 2008-10 and now the 6.7 Scorpion engines from 2011 to current.

From 1999 through 2007 the engine relied on a high pressure pump to get fuel up to the engine. This pump ran anywhere from 50 psi to upwards of 70psi with some simple Ford mods. In the 2008-2010 models with the entry of the 6.4 engine, Ford decided that 10psi would be enough pressure to supply the new high pressure injection pump. However, now with the 6.7 engine they have decided to go back to the high pressure roots and supply the engine with 60-65psi.

Let's start with the high pressure trucks: 1999-03, 2003-07 and 2011+. On these trucks we offer systems that will either bypass the stock high pressure pump and feed the engine its needed 50+ psi of fuel pressure or feed the stock high pressure fuel pump with 10psi thus allowing the stock pump to not work as hard to support higher fuel pressure demands.

The systems that will bypass the stock frame mounted pumps are:

For the low pressure units we have both Raptor and AirDog systems. The low pressure kits are available for all of the Ford applications. For the trucks that have a high pressure pump on the frame that pump fuel at 50 + psi, we use the low pressure units to feed them with constant fuel pressure. This not only helps the stock pump when trying to feed the engine with higher than stock fuel pressure, but it also prevents the stock pump from over working itself. On the 2008-2010 6.4 trucks, the stock frame mounted pump is already a low pressure pump, therefore when using any of our systems it will bypass the stock pump and supply the engine with 10-12psi of fuel pressure.

The systems that will feed the stock frame mounted pump are:

As for the installation of the systems, with the exception of the AirDog 150 kit, they will all pull from the factory sending unit eliminating the need to drop the tank and install a new suction tube. . Also on the AirDog II installs for both the 6.0 and 6.4 we tie into the factory return line, which does away with the need to cut into the filler tube for the AirDog II return.

For most all Fords, fuel pressure is their number one enemy. It's crucial to make sure you are running the proper fuel pressure needed for your application. For example, a truck with stock injectors and a programmer doesn't need 65-70psi of fuel pressure. Typically trucks under the 500 HP mark don't need more than 60psi unless the injector manufacture says otherwise. Also, all of the AirDog and AirDog II systems have a built in pressure port on the top of the base directly above the fuel filter, it's plugged with an 1/8″ pipe plug and can be removed and utilized to check pressure from.
