If the illumination of the check engine light is truly "related" to the fuel quantity, the issue might be a fault in the EVAP system. One way to find out for sure is to download the trouble code(s) that are stored by the vehicle computer whenever the check engine light comes on. If you schedule a check engine light diagnostic, the responding certified mechanic will download those codes and perform the required diagnostic to get this issue resolved for you.
