The present invention is directed to a funnel for use in refilling a vehicle fuel tank from a container. The funnel is adapted to be fixed to the fuel tank inlet so that a person adding fuel to the vehicle fuel tank does not need to hold it in place during the refilling operation. This allows a person to use both their hands to hold the container containing fuel and decant the fuel in a more controlled manner. The funnel also has an inlet opening where the peripheral rim is substantially horizontal when the funnel is fixed in an operational position. With the peripheral rim being substantially horizontal the funnel is able to receive and direct fuel into the fuel tank with minimal spillage.
