Hi all,
I am wondering if it is common or only for me. Everytime I refuel, gas flows back. It feels like there is another stopper inside the hole and it blocks the line. After several times of attempts I can finish fueling in the end though.
Anybody here who has same experience?
Do I have to put the nozzle in the hole at an certain angle or put it as deeper as possible? Please somebody tell me the secret.

Thanks!
