DESCRIPTION:
I have tried it and it works on about 70% of the gas stations. some more advance gas stations new ones when u press the pump there is no resistance. which means its not going to let any flow out because the valve is shut, but most of the time when u reach up to press what grade of fuel u need, and instead of pressing u just sqeeze the pump. it works!
Same way if u are done filling up your car. put the pump back for 2 seconds. lift it back up and put it in the car and squeeze and hold it while u lift the fuel Pipe behind u. this will use the gravity to put all the fuel towards the nozzle that was in the pipe and than in ur car.
this trick is best for Small engine cars. because they can get any where from 15 to 20 more miles worth of gas.
