Abstract: A method of attaching a fuel line to a fuel filter is disclosed herein.

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 groo

Abstract: A crawl space ventilation system includes an intake fan assemby (10) having a housing with an 8.times.15 inch tubular mounting portion (b 16), a jet-stream directing portion (30) which is substantially smaller than the mounting portion, and an electric fan mounted in the housing for driving air toward the jet-stream directing portion. The mounting portion is mounted in a crawl-space vent hole with the jet portion directed into the crawl-space toward a particular area to be ventilated. The crawl-space ventilation system also includes an outlet fan assembly (44) with an approximately 8.times.15 inch housing (46) and a jet-catching end (51). The outlet fan assembly also is mounted in a crawl space vent and is positioned to capture the air jet driven into the crawl space by the inlet fan assembly. Intermediate booster fan assemblies (70, 72) are also included to be mounted in the crawl space between vents for capturing and transmitting the jet stream between the inlet and outlet fan assemblies.
