Airdog II-5G 100 GPH Air Fuel Separation Lift Pump 98.5-04.5 Dodge 5.9L Cummins W/In-Tank PumpThe 98. 5 2002 Cummins got a pretty bad rap over the years for failed VP44 injection pumps, many claiming it was one of the worst decisions ever made to mate this supposed failure prone pump on a Cummins powered Ram.

The 98.5-2002 Cummins got a pretty bad rap over the years for failed VP44 injection pumps, many claiming it was one of the worst decisions ever made to mate this supposed failure prone pump on a Cummins powered Ram. Now, was it really the VP44's fault, or was the engine bay mounted lift pump really the culprit? In most cases, the failure of the low output lift pump causes the demise of the injection pump. And to make matters worse, they continued to use a similar lift pump placement all the way through the 2004.5 model years before going to a higher output in-tank lift pump. So how do you really fix one of these trucks for good? Easy, ditch the in tank stock lift pump and upgrade to an AirDog!

The AirDog II-5G is an all in one premium fuel pump and filtration system for your 1998.5-2004.5 Cummins diesel. This system removes water, particulates, and entrained air from the diesel fuel. The entrained air that is separated from the fuel is returned to the tank through a small return fitting. The fuel is delivered to the engine at the correct pressure and flow rate to meet the demands of the engine under all operating conditions.

The AirDogII-5G DF-100 systems feature a built in adjustable diaphragm pressure regulator. All AirDog II-5G systems include a complete installation kit. The AirDog II-5G, for this particular application, is preset at 17 psi from the factory for a stock application. The regulator is adjustable up to 55 PSI so you can fine tune the system to perfectly match up to your current and future performance upgrades.

HOW IT WORKS:
The AirDog II-5G DF-100 draws fuel from the fuel tank through a 1/2” suction line to reduce the risk of cavitation at the pump. The fuel is then drawn through the water separator where 92% of water is removed per SAE spec 1488. It is then pressurized through a Gearotor pump and sent to the 2 micron fuel filter before it is sent to the injection pump. The air from aerated fuel, due to tank sloshing and engine return lines, is separated and sent back to the tank through the 3/8” return fitting. The excess fuel that the engine does not use is recirculated through the diaphragm regulator back to the suction side of the pump.

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.

Absolute LIFESAVER.
Color: Black
A must-buy for any puppy owner that uses potty pads. Our pup still hasn't had all of her parvo boosters and has had to stay inside at all times. She is usually very good about going on her potty pads, but has a terrible habit of grabbing the pad and flinging waste everywhere and tearing the pad itself apart. This potty pad holder is PERFECT. It is sturdy and the grated tray fits in neatly. The dog is unable to get to the puppy pad, no matter how hard she bites or paws at the sides. Believe me, I've seen her try. We bought other puppy pad holders that were cheaper, but she was able to rip the puppy pad out of them easily. It is also really easy to clean. The plastic can easily be washed with soap and water or sprayed and wiped with antibacterial spray. The potty pad itself usually soaks up all of the urine, so there is never any worry of overflow. The only critique I have is that the rectangular shape is somewhat a poor design, because most potty pads are square-shaped. This means that the owner has to fold a standard potty pad in order to fit the tray. But this is not a huge problem, as we're still very happy with the product. Overall, it's worth the money, because now I don't have to worry about cleaning a huge mess, disciplining my pup for the behavior, or any health scares from her eating plastic from the potty pads. We loved the first one so much, that we bought a second one.

Perfect for what we need!
Color: Black
Love this. We have to leave our puppy home alone while we are at work. She’s tiny so I know she can’t hold it in the entire time we’re gone and I knew she would tear up the puppy pads. I came across this and it has been a game changer. She goes right on and does her business. One negative is when she only puts her front paws on and pees while half on the floor but that’s a quirk of the dog. The main negative is that if she poops, it’s sometimes hard to get it up and it gets in the holes. Plus is it’s easy to take apart and hose off. Definitely recommend!

Nice only if it's not warped
Color: Black
I bought three of these, and two are perfectly normal. One is warped like so many other reviewers say, and it is the bane of my existence. The top will not stay on, and when my dog tries to stand on it, it wobbles all over the place. Right now, we have it taped and bungee corded, and it looks ridiculous. I wish I would have returned it when I had the chance, and I really don't want to pay $40 for another, because that's a lot for a piece of plastic. Four stars for the normal ones, but dropping to three star rating because of the terrible quality control.

Life changing, $$$ saving!!
Color: Black
This tray changed everything for us. We have a WILD 6 month old pug. He is crate trained, but shredded puppy pads. Some days I went through 3 or 4 pads a day! Expensive, frustrating, bad for the dog's health. It took him a day to understand the tray, now he uses it 98% of the time-- he is not locked in the cage. I love this tray, and will buy another for upstairs when our pup is allowed to roam that far. The tray is easy to change, easy to wipe down and clean. Plus the pad can get fully wet before changing, not a little spot here and there, so 1 pad a day, not 4 shredded ones.
