This is the 2 micron AirDog replacement fuel filter that is a direct fit for all AirDog I, AirDog II, and AirDog II-4G models.
Cross Reference Numbers: (Note, this is for fitment and not micron rating):
Plugging of either the fuel filter or the water separator itself will cause low fuel pressure and low flow to the engine. If a low fuel pressure issue exists, replace the fuel filter. Typical fuel filter life is 15-20k miles depending on fuel quality. Remove the fuel filter by turning it counter clockwise. DO NOT pre-fill the fuel filter with fuel. The AirDog® will fill the filter and prime the system automatically. Follow the instructions on the filter for proper tightening procedures.
