Description

The PureFlow AirDog A4SPBF171 150GPH Air/Fuel Separation System for your 1999-2003 Ford 7.3L Powerstroke provides the most effective technology designed specifically to remove water, particulates, vapor and entrained air from the diesel fuel in your truck. The AirDog is a lift pump and filtration system, that enhances the fuel delivery to your engine with a commercial duty system.

Your high performance diesel engine demands higher fuel flows. Yet higher fuel flows increase the vacuum at the fuel pump and agitation in the fuel tank. These factors generate additional air/vapor in the fuel system preventing your engine from producing maximum power and efficiency. Additionally, air/vapor can cause galling and pitting of the injector barrel/plunger assembly and also tip erosion. The AirDog eliminates air in the fuel that robs your engine of consistently greater performance and can also cause permanent damage to your injectors. The AirDog also provides the fuel pressures and flows your diesel engine needs to produce maximum power, any time, every time!

The Airdog works by pulling fuel 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. Then, the fuel with only entrained air/vapor and tiny particulate contaminates remaining, enters the fuel pump. Under positive pressure flow, the fuel passes through the fuel filter and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated and returned to the tank. The clean fuel is now free of contaminants and water and flows at the proper pressures up to your engine. Each kit includes plumbing, hardware, wiring harness, mounting bracket and all components needed for installation.

Answer

AirDog and AirDog II 100 units are recommended for up to 500 horsepower.

AirDog 150 and AirDog II 165 units are recommended for horsepower up to 800.

AirDog II 200 units are recommended for anything that exceeds 1000 horsepower.

What are the differences between and AirDog and AirDog II?

The AirDog II aside from having the adjustable regulator, the pump and base assembly are designed different internally. The pump assembly has a Dual Inlet design allowing more fuel to flow into the Gerotor, this allows the pump to increase volume without having to work any harder. The base on the AirDog II is also much different. Internally the fuel is redirected through passageways after being pressurized, this allows less fuel to be returned to the tank and more fuel to be held in the filters for a true "On Demand" system.

Does this unit replace the HFCM on 6.0L Power Stroke applications?

Answer

The AirDog 100 Powerstroke Air/Fuel Separation System does not, but the Ford PowerStroke AirDogĀ®II Replaces OE Pressure Pumps.

What comes in the package? Is it just the fuel lift pump? Or lines, fittings, plugs etc. to hook it to the truck?
