Abstract
An engine fuel injection system includes a conventional fuel rail with a top feed fuel injector connected thereto. The overall length of the injector is able to be shortened by the application of compact fuel inlet filter mountings in which a well (deep cup) shaped filter element is positioned to overlap one or both of (1) an adjusting tube within the injector body and (2) a space between the end of the injector fuel inlet tube and the interior of the associated fuel rail. The filter may be fixed within the injector to the adjusting tube or the inlet tube or may be fixed externally of the injector to the fuel rail. Various exemplary embodiments are shown and described.
