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

An awesome quartz field watch for very little money
Color: Silver, Color: Silver
I really like this watch from Infantry. It is a sleek, cool stealthy design that goes well with any kind of outfit. It's got a Japanese movement inside it so you know the minutes don't "jump" around when setting it. Also, the date function on mine is still working just great. It's also got mineral glass instead of acrylic. Comes on a nice NATO strap too! Hard to believe it's only 20 bucks.

Best field watch for the price
Color: Black, Color: Black
The watch will display the day of the week in English or Spanish, but unlike similar watches sold on Amazon, it comes with clear instructions to let you choose the language. I don’t like NATO straps and the spring bars for the straps were impossible to remove without cutting away (use diagonal flush cutting pliers), which is the only reason for the 4 star rating, else it would be 5. I put a silicone quick release band on the watch and am very happy with it. The time is very legible, especially with the red highlight on the second hand. I like the 3D effect that shows between the minutes dial and the inner face. Very handsome/gorgeous and no-frills watch. You just can’t do better than this for the price.

Good watch, nice large numbers.
Color: Black
Nice watch. Not illuminated, but luminous hands and dial are easy to read at night. Day/date display is easy to adjust but must avoid doing so between 5PM and 9AM. Seems to be very accurate so far and time is fairly easy to synchronize. No problems with scratched crystal so far, and I wear this watch 24/7. Very long band should fit any size wrist.

Its just junk.. Quit working within 3 months of purchase. Took it apart and nothing looked bad, put in a new battery and still nothing. I didn't expect much considering the price, but you're practically throwing money in the trash buying this. Costumer service is non-existent if you're looking for a replacement. Amazon will always give money back with a returned item.
