<p>This method is for controlling a fuel supply system (S) on an automotive vehicle such as a truck (T), comprising a primary fuel tank (1), a secondary fuel tank (2), an intake fuel line (6) for feeding an internal combustion engine (E) of the vehicle, and a fuel return line (9) connected to either the primary (1) or the secondary (2) fuel tank. The respective fuel levels (L1, L2) in the primary (1) and secondary (2) fuel tanks are determined (S11, S21). This method comprises steps consisting in a) permanently connecting the intake fuel line (6) with at least the primary fuel tank (1), b) selectively connecting the fuel return line (9) to either the primary (1) or the secondary (2) fuel tank on the basis of at least the fuel level (L2) of the secondary fuel tank (2).</p> |
