The factory block mounted lift pumps found on the 1998.5-2004.5 Cummins have proven themselves as being nothing better than a temporary Band-Aid. Further, as the lift pumps failed, it would cause premature failure of the injection pump, a very expensive repair. While Dodge began retrofitting fuel pumps from the block to inside of the fuel tank, it has been shown that this conversion is better than the original units, but still not adequate, especially for those that have made any performance upgrades whatsoever. This pump kit is designed for those trucks that have the converted in-tank pumps and will deliver either 100 or 150 gallons per hour (GPH) of fuel, enough to support stock to 500+ rear wheel horsepower.

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.

IMPORTANT INFORMATION REGARDING IN-TANK FUEL PUMP:
This specific AirDog unit is designed for trucks featuring the in-tank lift pump. For those unaware, all of the 1998.5-2004.5 Cummins powered Rams came from the factory with a block mounted lift pump. However, if it ever failed and had it replaced previously, it very likely was retrofitted to the newer design that actually placed the pump in the fuel tank. If you're not sure where your pump is located, simply "bump" the key, which will engage the pump, then listen whether the hum from the pump is coming from the engine compartment or the fuel tank.

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

Lightweight, Comfortable All-Season Comforter for Everyday Use
Size: Queen, Color: Black, Size: Queen, Color: Black
After using this comforter for a few months now, I've found it very comfortable overall. While it is lightweight, it does provide adequate warmth on those cooler evenings. I do appreciate that it doesn't trap too much heat, meaning I've been able to use it comfortably in many different temperatures. The fabric of this comforter is soft, and it was very fluffy when I received it and ready to use. The design is quite simple and clean, with box-stitching to keep the filling in place; I did notice some spots where the filling does not seem to be filling evenly, but it has not affected how I feel about the comforter or how I have used it. It is easy to pull apart on the bed, so it doesn't feel bulky while making a bed. Because it is affordable and high quality, I think this is a good option if you are looking for low-maintenance comfort throughout the year. If you are looking for something that is thick and heavy like those found in hotel rooms, then this comforter may not be thick enough for your needs.

Great All-Season Comforter, Soft and Fluffy and Great Quality
Size: Queen, Color: Beige
This Comforter really surpassed my expectations by providing great value and quality which pleasantly nurtures me in my sleep. It provides a soft and fluffy fabric which makes a really comfortable experience for long periods of sleep. The color was spot on with no flaws and the fit was ideal. The comforter keeps warm nicely without overheating while also being cool if I’m too hot. The comfort surpassed other competitors with the softness and amazing qualities with no flaws in it. I would personally recommend it because it offers a lot without breaking the bank with its high quality and value and the comfort.

Soft, Fluffy & Perfect for Year-Round Use
Size: Queen, Color: White
I’m very happy with this comforter. It’s soft, lightweight, and fluffy without feeling too heavy or overly hot, making it great for all seasons. It gives the bed a clean, cozy hotel-like look and fits nicely inside a duvet cover thanks to the corner tabs. The box stitching helps keep everything evenly distributed, so it doesn’t bunch up after washing. It also washes well and comes out looking nice and fluffy again. For the price, the quality exceeded my expectations. Comfortable, breathable, and a great everyday comforter.

Comfy but gets lumpy after a wash
Size: Twin, Color: White, Size: Twin, Color: White
This comforter is great. Affordable, soft, fluffy, and just the right weight for snuggling up with. It loses a star for me because after the first wash, the filling has clumped leaving blobs in some areas and nothing in others. It looks lumpy on the bed and no longer covers evenly as far as thickness and heat. The empty spots allow too much cool air through.

Amazing quality, amazing price.
Size: Twin, Color: White
I bought this for my 5 year old and was surprised to see how high quality it was. I figured it wilds be thin because it was on the cheaper side, and it was an all season light one, but I was wrong. It it actually very plush and I plan to upgrade and buy myself one now lol. Great buy and great price. Its light weight, no smell, looks great ink the duvet, and fits perfectly on a twin. The hangover is beautiful. I will most definitely buy this again!
