AirDog FF100-2 Replacement Fuel Filter (2 Micron)

The Airdog FF100 and WS100 are the proper replacement filters for all (Airdog) & (Airdog II) fuel systems. (Light Duty Applications)

Filter Service Recommendations

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.

The Water Separator -

Replace the water separator every other time you change the Fuel Filter or if it becomes damaged or plugged. It is suggested to check/drain the water separator every three months or as needed should you experience excessive ‘water in fuel’ conditions. When installing the water separator, be sure to clean the under side of the AirDog® base. Follow the instructions printed on the pre-filter for proper tightening procedures.

Caution: Be extremely careful to prevent any contaminates or debris from entering the pre-filter when removing it for cleaning! Large debris will jam the Gerotor and cause the fuse to blow. This is not a warranty item. Should this happen, you can easily put the system back into working order. See the instructions on “How to clean the Gerotor” for proper procedures.

The Fuel Filter -

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.
