I usually go to a full service gas station because its not an option to pump it yourself,yesterday told the guy to fill it up and after he was done he pulled so hard on the nozzle that the plastic piece inside flew out,took a few minutes to align that plasic piece inside correctly,it seems o.k now but was curious if this has happened to anyone considering its an important piece to prevent any gas from leaking,you could also see the gas at the bottom,appreciate any inputs,BTW the guy was able to keep his teeth,wife and kids in the car.
