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.
The patented AirDog® II system removes entrained air/vapor from diesel fuel which improves engine performance by:
Maintaining Correct Injection Timing
Eliminating Spray Pattern Disruption
Allowing for a Full Power Stroke and Complete Burn
Which leads to:
Increased Fuel Economy
Increased Power Output
Increased Torque Output
Longer Injector Life
Improved Throttle Response
Reduced Exhaust Emissions
Optimized Engine Performance
AirDog® II also overcomes loss of power for diesel engines operating at higher altitudes.
The AirDog® II Fuel Air Separation System is a one of a kind product that features Demand Flow Technology and an Adjustable Regulator that lets you fine tune your fuel system for increased fuel economy, power, and performance!

AirDog® II 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 gerotor fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining, then 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 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.
