Abstract
An improved thermal relief vent for a fuel tank, and a method of manufacturing the same, includes a thermal relief ring that is used to create a mechanical seal within the vent. The thermal relief ring, at room temperature, is crimped in place by use of the vent cap itself. The crimped thermal relief ring creates a mechanical seal between the vent and the vent cap, up until a predetermined thermal relief point, at which time the thermal relief ring will soften and/or yield and release the vent cap from the vent body.
