Servicing the FCC
The frequency of draining the water or replacing the fi lter
element is determined by the contamination level of the
fuel. Replace the
fi lter element at least once a year, or
when a loss of power is noticed (whichever occurs fi rst).
WARNING
Improper use, installation or servicing may cause an
explosion or
fi re resulting in bodily injury, or death.
This unit should only be serviced by a quali fi ed
technician. Read and follow all instructions before
proceeding. Run the engine and check for fuel leaks
after installation, element replacement or draining
the bowl. DO NOT remove the FCC bowl unless
servicing the
fi lter element, otherwise contamination
or bowl O-ring swelling may result.

1. Disconnect the two-wire electrical connectors
from the FCC and the Low Pressure Fuel Pump
