Description
Beginning in 2005, Ram made a change that moved the factory lift pump from the side of the engine block into the fuel tank to aid in fuel pump longevity. While this change was a move in the right direction, the factory pump is still underrated, especially for trucks that have been slightly modified. This frame-mounted lift pump will deliver 100 or 150 gallons per hour (GPH) of fuel, enough to support a stock truck all the way to over 500 rear-wheel horsepower! AirDog 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, which contains entrained air, particulate contaminants, and unknown quantities of water. Diesel fuel passes through the water separator, which removes the large particulate contaminants that could damage or jam the gear rotor fuel pump. The fuel, now with only entrained air/vapor and tiny particulates remaining, goes into the gerotor pump, which then leads to the fuel filter. As the fuel passes through the filter media, the remaining particulate contaminants are caught, and the entrained air/vapor are also separated. Through the positive fuel air separation features of the patented AirDog 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 scrubbed free of contaminants and power-robbing air/vapor. At pressures and flows able to meet the engine's needs, it exits the fuel filter through two passageways. First, the fuel for the engine passes into the fuel pickup tube and off to the engine. Then, the excess fuel not needed by the engine is recycled internally through the pressure regulator back to the water separator. Gallons Per Hour Option: 100 GPH / 150 GPH- The GPH that is best for you is determined by the Horsepower rating of your truck. You can consult your owner's manual or manufacturer's website if you haven't done any aftermarket alterations. Otherwise, you can consult guides or do a dyno test for an accurate and current measurement.  Still 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 100hp injectors or larger(500hp+), you will want the 150. If you have any questions, give us a call.

About AirDog by Pureflow
PureFlow Technologies aka Airdog has established themselves as one of the œgo to companies for factory replacement and upgraded fuel pumps for the light duty diesel performance truck market with their AirDog and Raptor lines. If you are looking for just a reliable source of fuel, their Raptor stand alone pumps are the answer. You guys with 1998.5-2002 2nd Gen Cummins diesels equipped with Bosch VP44 injection pumps know how important this is to avoid pump failure. When lift pump pressure drops below 5psi you run the risk of ruining the expensive VP44 injection pump. The Raptor fuel pump gives you peace of mind with a LIFETIME WARRANTY , a built in ADJUSTABLE REGULATOR that supplies a constant 15-17psi available in flow rates of 100 and 150 GPH, complete truck specific installation kit with no drill mounting brackets and standard ½ big line kit included.

For those of you that prefer the added security of having a filter system to go along with your lift pump, PureFlow offers the AirDog and AirDog II systems. The original AirDog® provides a cost effective technology designed specifically for diesel pickups to remove water, particulates, vapor and entrained air from diesel fuel. The AirDog® replaces the Cummins factory lift pump and filter system, and enhances the existing fuel delivery and filtration system for Powerstroke and Duramax engines. Your High Performance diesel engine demands higher fuel flows. Yet, higher fuel flows increase the vacuum at the fuel pump and agitation in the fuel tank. These factors generate additional air/vapor in the fuel system preventing your engine from producing maximum power and efficiency. Additionally, air/vapor can cause galling and pitting of the injector barrel/plunger assembly and also tip erosion. The AirDog® eliminates the air in the fuel that robs your engine of consistently greater performance and can also cause permanent damage to your injectors. The AirDog® also provides the fuel volume your diesel engine needs to produce maximum power, any time, every time! Increased diesel fuel economy, reduced emissions and increase power output are the net results.

The AirDog II system improves on the original AirDog by offering demand flow, so that the unit only draws as much fuel from the tank through the tank module as is required by the engine, and then returns only air and a dribble of fuel to the tank. What does this mean? Connecting to the tank module means there is no need to drill holes in the fuel tank to install an aftermarket fuel draw straw, so installation with the included fittings is QUICK and EASY. The AirDog II also features either a preset or adjustable stainless steel pressure regulator. As always, all AirDog II units come complete with fittings, fuel lines, mounting brackets, and full-color installation manual specific to each model truck.

We have fielded numerous calls regarding model years 1998.5 2004 Dodge trucks modified with in-tank fuel pumps. To facilitate an easier installation, Pureflow offers models available for 1998.5 2004 Cummins that are standard without an in-tank pump, or that have been modified with the in-tank pump. Please note that this option applies to 100 GPH models only, as the higher-flow models (150 GPH and up) will still come standard with the suction tube kit and bypass the in-tank pump anyway.

And finally, for the 1998.5-2002 Cummins owner that has a failed factory, block mounted pump, and merely looking for a stellar upgrade over stock, but not wanting to jump into a frame mounted system, the Factory Replacement Raptor is your answer. This features 100 GPH of reliable fuel delivery and mounts in the factory location for ease of installation. The FRRP is a great alternative for those only running a programmer and are not concerned with additional filtration. This unit only comes with a four year warranty, in contrast to the lifetime warranty of Pureflow's frame mounted systems.
