On-Chassis Fuel Filter (Fuel Pre-Filter) - Ford F-MAX User Manual

On-chassis fuel fi lter (Fuel pre-fi lter)
Fuel pre-fi lter performs the initial fi ltration
of the fuel drawn from the fuel tank. Also,
it separates the water inside the fuel and
provides fuel separated from water to the
engine.
Filtered water is collected in the container
under the fi lter assembly.
MAINTENANCE AND SERVICE
If the "water in fuel" warning light
illuminates when the ignition is on, loosen
or unclip the integrated water sensor
under the fi lter assembly and close it when
clean fuel appears.
Tighten the water sensor securely when
you are closing the tap. Otherwise, air may
enter the engine, and this may cause fuel
leak.
WARNING
Care that is shown for the cleaning of
the fuel fi lters will contribute the service
life of main fuel fi lter on engine and fuel
system of the engine.
