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 qualifi 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.
Draining the FCC Bowl, ENGINE OFF
1. Disconnect the two-wire electrical connectors
from the FCC and the Low Pressure Fuel Pump
(LPFP).
2. Remove the 7/16” plug, and drain the bowl
contents into an approved container.
CAUTION: Both fuel and water will drain from the
FCC bowl.
3. Apply pipe sealant, suitable for use with gasoline,
to the threads of the 7/16” plug.

WARNING
Extreme caution must be exercised when servicing
the fuel system. The fuel system operates under
high pressure. Use caution when removing or
replacing components, as residual pressure may be
present.
