I was listening to "Car Talk", as I usually do on Sunday. And, they had a big thing about new tires, static shocks. And the thing I found interesting was accessory ground straps that hang from your car that yuou can install. Because the tires are giant insulators there's no dicharge. But they act like your sneakers when you were a kid shuffling around on carpet picking up static charge, so you could see the neat spark at the door knob. But why it did not discharge through all the things she did up to the flash point, I don't know. The answer might be her shoes, that might be insulating enough to not allow discharge. But contact from her butt on the car, hand to pump was. Now, i just went out to by van , and noticed that that the filler hole, tube, and my gas tank are plastic! I did notice that there is a wire there that runs into the tank from metal flap at the hole, and goes out to the frame. Maybe there's no cantact there?
