Section 8 Fuel Filter & Pre-filter
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 underside 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.
CAUTION: DISPOSE OF WASTE FUEL AND USED FILTERS PROPERLY TO
PROTECT OUR ENVIRONMENT!
