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. 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.

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.

Reliable Essential for Gentle, Everyday Care!
Scent: Baby Fresh, Size: 72 Count (Pack of 1), Scent: Baby Fresh, Size: 72 Count (Pack of 1)
Pampers Complete Clean Baby Fresh Scented Wipes have become a staple in our routine, and for good reason. From the very first use, it’s clear these wipes are designed with both effectiveness and gentleness in mind. They strike a thoughtful balance—strong enough to handle messes, yet soft enough for a baby’s delicate skin. What stands out most is their versatility. These wipes truly live up to the “head to toe” promise. Whether it’s a quick diaper change, wiping sticky hands after meals, or freshening up on the go, they handle it all without irritation. The texture is just right—not too thin, not overly thick—and they don’t tear easily during use. The light baby fresh scent adds a clean, comforting touch without being overpowering. It leaves your little one smelling refreshed rather than artificially perfumed, which is something many parents appreciate. Another highlight is how moist they stay. Even after opening and closing the pack multiple times, the wipes retain their hydration well, making each use consistent and reliable. There’s no need to use multiple wipes for a single cleanup, which makes them both practical and cost-effective. Overall, Pampers Complete Clean wipes deliver exactly what parents look for: dependable cleaning, gentle care, and a pleasant experience with every use. They’re a small but meaningful upgrade to everyday baby care.

Very happy with quality and strength
Scent: Baby Fresh, Size: 72 Count (Pack of 12)
Fantastic wipes. These are super thick and clean up baby great. These are the only thing that do not cause a rash on baby. Do not leave a sticky feeling after use. Smell is strong, not the best but not terrible. I can deal with it for the quality of the wipe.

Great for pets and pollen
Scent: Baby Fresh, Size: 72 Count (Pack of 1)
I use these to wipe down the pets when they come back inside. These are especially useful during pollen season. You can see the pollen and/or dirt on the wipes. This is much better than having it all over the house. I love that they are unscented; I do not have to worry ablut these causing any irritation. They are moist enough to do the job without leaving the prts wet or with any residue. And, baby wipes are just as effective and MUCH cheaper than buying wipes that are marketed specifically for pets. 5 stars
