Airdog 4G Air Fuel Separation System 89-93 Dodge Ram 5.9L Cummins12 Valves are fun, aren't they? With a few mechanical changes, you can unleash all kinds of power. If you keep pushing the limits of fueling, before long you will surpass the capabilities of the stock mechanical pump. In these instances, or if your stock pump is getting weak, its time to upgrade to an Airdog lift pump. This pump is designed to deliver up to 150 gallons per hour (GPH) of fuel at 10 13 PSI.

12 Valves are fun, aren't they? With a few mechanical changes, you can unleash all kinds of power. If you keep pushing the limits of fueling, before long you will surpass the capabilities of the stock mechanical pump. In these instances, or if your stock pump is getting weak, its time to upgrade to an Airdog lift pump. This pump is designed to deliver up to 150 gallons per hour (GPH) of fuel at 10-13 PSI.

AirDog I-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 I-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.

Unsure of whether you need the Airdog 100 or the Airdog 150? - Put it this way...if your truck is stock, or moderately stock(up to 500hp) you want the 100. If you've added a 100hp injectors or larger(500hp+), you will want the 150. If you have any questions, give us a call

Not paper thin like most T-Shirts
Color: Light Khaki, Size: X-Large
These Cooney tshirts are really nice. Feel like 100% cotton and keep their shape and color. Size true to fit. Good value for the money. Love the mock neck style. Bot a couple one in white and one in black. Then went back and ordered 6 more various colors. Like the all.
