Section 8 Fuel Filter & Water Separator
Filter Service Recommendations
Plugging of either the fuel filter or water separator will cause low fuel pressure and flow to
the engine. Should you experience low pressure, first check the water separator for plugging
and restriction. If the low fuel pressure issue continues, replace the fuel filter.

The Pre-filter
The AirDog® wire screen water separator/pre-filter is serviceable and does not
need to be replaced as does the fuel filter. Replace the water separator only if it
should become damaged or defective. Servicing of the water separator simply
requires draining at regular intervals. It is suggested to check/drain the water
separator every three months or as needed should you experience excessive
‘water in fuel’ conditions. When re-installing the water separator, be sure to
clean the under side of the AirDog® base. Follow the instructions printed on the
water separator for proper tightening procedures.
Caution: Be extremely careful to prevent any contaminates or debris from
entering the water separator should it become necessary to remove it for
cleaning! Large debris will jam the Gerotor and cause the fuse to blow. This is
not a warranty item. Should this happen, it is easily put back into working
order. See the instructions on “How to R & R 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 the environment!
