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.

We claim: 1. A thermal relief vent comprising: a rigid vent body; a vent cap secured to said rigid vent body; and a ring of thermal relief material that defines a mechanical seal between said rigid vent body and said vent cap, wherein said ring is manufactured prior to placement in said vent as a solid ring of thermal relief material; the vent further comprising a spring, a vent valve and a float positioned within said vent body; wherein said float includes a top surface positioned adjacent said vent valve and a side surface having a protrusion extending therefrom, said float including a seal secured to said protrusion and extending over said top surface of the float.
