The AirDog I-4G is the latest in fuel delivery for your GM 6.6L Duramax! Its patented design has been quality engineered to remove entrained air and water vapor from diesel fuel. The result is a compact, long lasting, efficient, and quiet fuel system made with superior quality.

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 programmer or larger(500hp+), you will want the 150. If you have any questions, give us a call

Good chew toy for an aggressive chewing dog
Size: Large
Well built for an aggressive chewing dog. I wouldn't say indescribable but it has lasted longer than all other chew toys he's had.

Ball is heavy due to solid construction
Size: Large
Just received the large ball. Construction appears to be excellent and time will tell with my aggressive chewer. That being said I ordered the large because our Mini Goldendoodle loves playing with our daughter’s dog large ball. I may not have read description close enough but ball is solid and weighs a considerable amount. Our dog soon learned to pick it up but I’m just disappointed that it isn’t hollow like ones our daughter has.

Love this
Size: Medium
My dog is a beast and loves to shred through any toys we get him but with this it’s keeps his teeth busy and off the furniture and there is no signs of any damage. Super high quality and perfect for any fur baby that’s loves to chew
