Abstract
A vent apparatus is adapted to be coupled to a fuel tank and includes a valve housing made of a non-weldable plastics material and containing a valve. The vent apparatus further includes a tank mount made of a weldable plastics material and coupled to the valve housing. The tank mount is adapted to be welded to an underlying fuel tank to support the valve housing within a mounting aperture formed in the fuel tank. The tank mount is coupled to the valve housing by a retainer ring formed to include an annular channel opening toward the valve housing. The valve housing includes an annular upper flange extending into an upper region of the annular channel formed in the retainer ring. The tank mount includes an annular lower flange extending into a lower region of that annular channel to mate with the overlying annular upper flange and trap a flange seal therebetween.
