AirDog II Fuel Air Separation System Featuring Demand Flow Technology

airdog2flow.jpg

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 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-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.

Dodge Makes and Models - Cummins Diesel

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.
