Ford Australia, like many manufacturers, doesn’t like the idea of fitting auxiliary fuel filters. The official line is that the smaller-micron filtering of these units isn’t compatible with the pressures the injection operates on. But our expert spanner-twirlers reckon a finer filter is okay if it’s fitted upstream of the high-pressure pump (ie; between the pump and the fuel tank). It’s no guarantee that you’ll never get dirty fuel in the engine, but it’s a hell of a lot better than nothing.
Also, don’t ignore a check-engine light, as sometimes, a damaged injector-pump return valve can stick and overheat the fuel, sending the vehicle into limp-home mode.
