<p>In a fuel tank structure for an automotive vehicle, a fuel collector unit (1) includes a collector body (3) which is provided with a fuel collecting chamber and a fuel passage. The fuel passage has an inlet adjacent to a bottom wall of a tank body and an outlet opening toward the fuel collecting chamber for conducting fuel in the tank body (203) into the fuel collecting chamber. The fuel passage is arranged such that the fuel below a predetermined vertical level at a certain location in the fuel passage is prevented from flowing out through the inlet. The fuel collector unit further includes an ejector which ejects oversupplied return fuel into the fuel passage through the inlet so as to suck the fuel therearound. The sucked fuel is mixed with the ejected return fuel and introduced into the fuel passage through the inlet.</p>
