Abstract

A fuel tank venting system includes a fuel cap, a vent diaphragm and a vent disc. A valve cavity with a substantially concave bottom is formed in a bottom of the fuel cap. At least one air passage is formed through the vent disc. A substantially convex surface is formed on a top of the diaphragm projection. The vent diaphragm is retained between the substantially concave bottom and the substantially convex surface. When air is needed for fuel flow, a vacuum within the fuel tank pulls the perimeter of the vent diaphragm downward, which breaks a seal with the substantially concave bottom to allow air flow. In a second embodiment, the fuel tank venting system is contained in a wall of the fuel tank. In a third embodiment, the fuel tank venting system is contained in a fuel vent body, which is attached to the fuel tank.
