The stock fuel pump may be adequate for a stock truck, but if as soon as you try to gain a bit more power, the pump might start causing fuel starvation problems. To solve this issue, Airdog II-4G DF-165 has a fuel flow of 165 gallons per hour, meaning your engine is never going to skip a beat. Not only that, but the precise injection improves several aspects of engine operation, allowing for a full power stroke and a complete burn.
This results in more torque and horsepower for a noticeable difference in performance. Throttle will become more responsive and the engine will operate smoothly when idle. Thanks to the better fuel consumption, you’ll also experience a reduction in exhaust emissions, which is a very important aspect. Boasting one of the quietest lift pumps, the Airdog’s II-4G DF-165 is an option you’ll truly appreciate!
If you’re going with an aftermarket lift pump, why not replace the stock filters as well? The Airdog II-4G DF-165 comes with a fuel-air separation system consisting of the WS100 water separator and the FF100-2 fuel filter with a tolerance of 2 microns.
Now you’ll not only get the ideal amount of fuel to the engine no matter the situation, but also the cleanest fuel possible. This will significantly extend the durability of your engine, especially the fuel injectors which are an expensive component to replace. Save in more ways than one with the Airdog II-46 DF-165 fuel system.
The Airdog II-4G DF-165 has one of the best warranty policies out of any lift pump system. A limited lifetime warranty has you covered should any manufacturing issues or craftsmanship errors emerge. Drive with full confidence in your fuel system by installing the Airdog’s excellent lift pump!
Does this require any additional pump, like a lift pump or?
No, this pump will include all components needed to complete the installation including: Fuel pump system, fuel lines, wiring harness, mounting brackets, etc. It is a lift pump in conjunction with all necessary filters and fuel delivery.
Does this require the purchase of a regulated return system to be installed? If not, is it recommended to buy one?
A regulated return setup is not required as the Airdog system has an internal fuel return. However, it is still recommended to run a dedicated fuel return system (regulated) for peace of mind.
What is the difference between an Original AirDog and AirDog II 4G?
The AirDog II 4G aside from having the adjustable regulator, the pump and base assembly are designed different internally. The pump assembly has a Dual Inlet design allowing more fuel to flow into the Gerotor, this allows the pump to increase volume without having to work any harder. The base on the AirDog II is also much different. Internally the fuel is redirected through passageways after being pressurized, this allows less fuel to be returned to the tank and more fuel to be held in the filters for a true “On Demand” system. An intermediate shaft was also incorporated to completely separate the electric motor from fuel path along with an additional two bearings to reduce drag and increase reliability and lifespan of the AirDog II 4G
If I daily drive my stock truck will running an AirDog 150 or AirDog II 165 4G hurt anything?
No, it will not hurt anything. With the Original AirDog’s High Flow return all excessive fuel not being used by your truck will be returned to the tank. When running the AirDog II 4G the Demand flow only allows the pump to send what fuel is needed to the injection pump, and all other fuel is recirculated internally in the base returning it to the suction side of the pump.
