WHEN FILLING GAS TANK (TOPPING IT OFF) I'LL HEAR 1 CLICK AND THE GAS WILL INSTANTLY START SPEWING OUT. NORMALLY IT'LL RUN DOWN THE VEHICLE (WHICH HAS CAUSED PAINT DAMAGE/RUST). HOWEVER, LAST WEEK I WAS PUMPING GAS AND I RECEIVED ABSOLUTELY NO WARNING THAT IT WAS FULL SO THE GASOLINE STARTING BLOWING BACK AT ME. I WAS SATURATED FROM MY ARMS TO MY FEET IN GAS. IT WAS ABSOLUTELY TERRIFYING, NOT TO MENTION EXTREMELY DANGEROUS, AND HUMILIATING. SOMETHING NEEDS TO BE GONE BEFORE SOMETHING TRAGIC HAPPENS TO SOMEONE.
