Abstract: A one piece vent formed from one integral piece of material, such as Aluminum, and which defines a fluid pathway therethrough having a borehole within said fluid pathway, and further including a crimp that secures a ball and a float within an interior of the vent, the float movable between a sealing position on said borehole and an unsealed position away from said borehole.

Abstract: A one piece vent formed from one integral piece of material, such as Aluminum, and which defines a fluid pathway therethrough having a borehole within said fluid pathway, and further including a groove that retains a roto clip therein so as to secure a ball and a float within an interior of the vent, the float movable between a sealing position on said borehole and an unsealed position away from said borehole.

Abstract: The present invention relates to an integrated anti-siphon fuel filler neck assembly that includes wedge shaped apertures and a side wall that includes side wall apertures connected to the wedge shaped apertures, wherein the wedge shaped apertures and the side wall apertures are sized to prevent a siphon hose from passing there through.

Abstract: A low profile elbow, and a process of manufacturing the same, includes a tube secured at two different location in two different planes of a base, wherein an end surface of the tube is positioned at an acute angle with respect to a tube axis, and wherein the tube defines a center of curvature positioned lower than a lower surface of the base.

Abstract: The present invention relates to a flange that includes a base region, a raised region, and a sloped region there between. The sloped region includes concave and convex curved regions positioned in a plane parallel to an elongate axis of the flange, and concave and convex curved regions positioned in a plane perpendicular to the elongate axis of the flange so as to reduce stress within and fatigue failures of the flange.

Abstract: The present invention relates to a flange that includes a base region, a first raised region, a second raised region, a first sloped region between the base region and the first raised region, and a second sloped region between the base region and the second raised regions, wherein the first and second sloped regions extend through a gap region between the first and second raised regions, and wherein the first and second sloped regions define multiple concave and convex regions in multiple planes of the flange so as to reduce stress within the flange.

Abstract: A servicable draw and return tube assembly for use in fuel tanks is disclosed. The assembly may include a draw tube and a return tube secured to a plate, wherein the plate may be removably secured to a flange, which is fixedly secured to a fuel tank. The process of removably securing the plate to the flange allows for use of different sizes and materials to be utilized in manufacture of the assembly, thereby saving installation time and manufacturing costs.
