<p>A pressure relief valve and a mating fuel tank bung are installed directly on a fuel tank. In one embodiment a bung is welded directly to a fuel tank, and thereafter a pressure relief valve is attached directly to the bung by mating threads. This system and installation method provides a cost and time effective installation process that is expedient, does not require additional pipes or plumbing fixtures, and the resulting installed valve may provide improved safety features due to the exclusion of additional pipes and plumbing positioned between the valve and the fuel tank and a compactness of design.</p> |
