<p>In a two piece valve assembly (14) comprising a non-weldable lower body portion inserted into the fuel tank through an opening (12) in the tank wall (10), and an upper valve body portion or cover (20) made from a weldable material and designed to be connected to the lower valve body portion (16) and welded to the upper surface of the fuel tank wall (10), an improved assembly structure comprising a plurality of circumferentially-spaced support/retention tabs (26) are formed on the lower valve body (16). The support/retention tabs (26) allow the lower valve body (16) to rest on the upper surfaces of the fuel tank wall (10), and strengthen the well connection between cover (20), lower valve body (16) and the fuel tank wall (10).</p> |
