Having a real problem trying to fill gas tank. Pump will kick off just like it does when tank is near full. Problem is its taking 15 min plus to fill tank. We've tried to keep it full, and run it almost empty. Either way, as soon as you start flow it keeps kicking pump off. Is there some kind of sensor?
