Molded reservoir support structure coupling

A fuel tank, comprising:

• a fuel tank wall at least partly defining an interior for holding fuel, having an anchor with a side wall, having at least one first flange projecting generally laterally from the side wall, and having at least one clearance located at the side wall adjacent the first flange;
• and
• a support structure constructed to brace the fuel tank wall and having at least one second flange projecting generally laterally therefrom;
• wherein the first flange, the second flange, or both, have a raised portion, and the first flange, the second flange, or both, that is free of the raised portion has a segmented annular portion;
• wherein, to interconnect the fuel tank wall and the support structure, the support structure is inserted into the anchor and the second flange passes through the clearance, and the fuel tank wall, the support structure, or both, are rotated and the raised portion and segmented annular portion are initially lapped about each other, and upon further rotation, the raised portion is bent toward an unraised position and the first flange and the second flange lap over each other.
