Tried the bursts of air in vent opening. What should I experience? The first burst or two, air comes out of main filler hole. Once I take my finger and air nozzle off of vent opening, rest of air seems to come out there. What is this valve you mention? The one in the fuel cap? I blew into all those like a straw and they allow airflow in one direction or the other… I don’t understand the fuel gauge being pegged at full.
