A capless fuel filler system 20 comprises an inlet at an exterior end of a filler pipe 22. Inlet 21 is closed/opened by a flap 23 hinged at 24 to move between a closed position blocking filler pipe 22 and an open position where a fuel filler nozzle (not shown) can be inserted into filler pipe 22. System 20 comprises an electrical heating element 30 which can generate heat to melt ice that may have formed on flap 23, holding it in the closed position. Power may be supplied continuously; on demand by a manual switch; or for a fixed period of time. Power may also be supplied in response to ambient temperature; having low power below a first temperature threshold, and optionally higher power below a second threshold. Power may also be turned off above a third threshold higher than the first threshold.
