A fuel pump module and method for mounting such to a fuel tank having a limited mounting depth, includes a reservoir, a modular flange, and a compressible coupling element, wherein the modular flange and the reservoir containing the fuel pump are connected offset to each other vertically, by means of the compressible coupling element. Upon installation in a shallow fuel tank, the offset attachment provides for the reservoir, to be biased against the bottom wall of the fuel tank without vertically interfering with the modular flange embodying various components such as vent valves or carbon canisters, which after mounting, are at least partially adjacent horizontally to the reservoir within the fuel tank.
