The Ford Fusion fuel filter should be replaced every 15,000 km or every 12 months. It is recommended to replace the fuel filter as basic maintenance, and complicated tests are not necessary if the filter is already known to be old. The fuel system is depressurised so the filter can be removed from the high-pressure fuel line without gas spraying out. The in-and-out connectors to the filter are removed and the filter is removed from the fuel line. The new filter is installed using a small amount of oil on the O-rings to ease re-installation of the quick connect fittings.

What You'll Learn
Depressurising the fuel system
Before removing the filter, it is important to consult the vehicle maintenance schedule to determine when to replace the fuel filter. If the car has sat unused with gas in the tank for more than three to six months, the gas should be drained and the fuel filter replaced. If you have bought contaminated gas, once all fuel system repairs are made, always install a new filter. Gasoline is perishable and will eventually degrade into compounds that will damage the fuel system.
When the old filter has been removed, a new filter is installed using a small amount of oil on the O-rings to ease re-installation of the quick connect fittings. The fuel system is then checked for leaks while the engine is running. If there is a leak, have it repaired before driving the car. If clogging is suspected and potentially causing engine operating problems, have the cause investigated and resolved as soon as possible.
