Water Separator Benefits
A water separator makes sure that only clean fuel arrives at the engine for ignition. Without it, your engine is at risk of having its lifespan shortened, on top of reduced performance and power. There’s no need to risk expensive repairs, simply install the Airdog Water Separator and keep your engine running smooth and to its fullest potential.
Is this the replacement for all Airdog systems?
Yes, this is the replacement for all Airdog I, II, and II-4G systems
Does the water separator self-prime?
Yes it does, but for the first install, it's recommended to pre-fill it with diesel.
Do I need a new separator when I change the fuel filter?
Not necessarily, but that’s like cleaning half your injectors. Its recommended to replace the filter and water separator together. Its cheap insurance.
