Abstract
A connection for attaching a fuel line to a fuel filter having a tubular coupling base affixed to a filter and having an intermediate portion providing wrench fiats, one end being connected with a fuel line, the coupling base being further defined by an annular surface adjacent the wrench flats forming a shoulder surface and an annular reduced diameter groove in the annular surface; a bracket of thin, stiff material having an opening therein receiving the coupling base annular surface, an inner surface of the bracket engaging the coupling base shoulder surface, the bracket having a fuel line receiving notch; a retaining ring positioned in the coupling base groove to engage the bracket and thereby secure the bracket to the coupling base; and protrusions in the bracket adjacent the opening providing an interfering relationship between the bracket and the coupling base shoulder surface to resist rotation of the bracket relative to the coupling base when the retaining ring is in position in the coupling base groove.
