Welcome. There have been issues with Subaru fuel lines becoming loose, especially in the Impreza. You might want to check clamps and such near your fuel filter and just make sure everything is tight.
Forester owners have had the issue sometimes also. It happens more often when the temp gets cold outside and the lines shrink a bit.
