Hey guys. I'm having issues with putting gas into my car. I start to put gas in it and it will just randomly shut off. Sometimes not even after I've gone 50 cents. What could be the problem? Sending unit, sensor or what? Please help me out guys.

 

probably the vent hose..

 

Is the car running while putting gas in? I find with mine that my car has to be off to fill it. If my car is on while pumping gas, it shuts off after every few cents. Hope this helps!
