AirDog® II-4G Fuel Air Separation System featuring Demand Flow Technology and Enhanced Features

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 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® 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.

High quality item
Size: 13 Years, Color: Light Blue
My granddaughter is 12 years old and loves these types of jackets for school, as the AC is cold. The color (baby blue, which was her personal request) was beautiful and the quality was excellent. The size 12 was a perfect fit.

Sizing is not accurate!
Size: 9 Years, Color: Light Blue
I bought this for my granddaughter, who is 8 years old, and typically wears a size 8. I purchased the size 9, she likes oversized hoodies, even though the add already says it’s oversized. It was MAYyBE a size 6, it was tight on my six year old granddaughter. I sent it back, and am not reordering. I’m not going to keep guessing on sizing. I want to know that when I order the size she wears in Nike, Adidas, Target,etc. , that it’s going to be the same, and not have to keep returning items…

Loved these and they fit. Nice and warm for a chilly summer evening at the beach, and looked great with summer pastels.
