AirDog by PureFlow

Diesel fuel contains varying degrees of entrained air in the form of foam on the surface or suspended in the bulk fluid as tiny bubbles. Additionally, fuel is driven into the fuel pump by atmospheric pressure, which is usually only enough pressure flow to fill the pump at idle speeds. Consequently, at higher operating RPM's, the stock pump cavitates producing vapor. The AirDog overcomes the inadequacies of the conventional vacuum feed system. Removing the entrained air and preventing vapor from cavitation restores injection timing and engine performance to ensure maximum power output and peak efficiency at all times!

With 3 units to choose from, PureFlow has you covered. The AirDog can be used for any application, whether you're stock or modified; you still get the engineering and results behind the system. The AirDog II-4G features many innovative improvements for increased pump performance, less noise and less maintenance. The AirDog II-4G utilizes an intermediate pump shaft that moves the electric motor away from the fuel. This eliminates any potential for "wet motors" due to a damaged or leaking seal. The Raptor is a great way to move the fuel from tank to injector at a pressure you can regulate for optimal performance and safety. All three units are designed and manufactured impeccably, include everything you need to install it and come with a warranty to back it up.
