I just tried to pump gas for the first time in my Inscription which had an empty tank. The pump got to about 20 liters before stopping as though the tank was full. This happened several times, and I gave up at around 30 liters pumped because I was in a rush. I tried pulling the nozzle out a bit, and it didn't help. I did a quick search, but couldnt find anything similar. Is this a known issue?
