I don't know if it is the same as the ZX5 but the fuel filter in my 2005 ford focus ST has the fuel filter in the fuel tank, because it is an automatic. A manual has the fuel filter in the fuel line and you should be able to find it by following fuel line.
To change the fuel filter on a 2006 Ford Freestar, first, relieve the fuel system pressure by removing the fuel pump relay and starting the engine until it stalls. Next, locate the fuel filter, which is typically found along the fuel line under the vehicle. Disconnect the fuel lines from the filter using a fuel line disconnect tool, then remove the old filter and replace it with a new one, ensuring the flow direction is correct. Finally, reconnect the fuel lines, reinstall the fuel pump relay, and start the engine to check for leaks.
Fuel Filter Location The fuel filter is located along the frame rail under the vehicle and is accessible only from underneath the vehicle.
