my girls hyundai has an issue with pumping gas. there is this little ?charcol? air breather canister thing that keeps cloging the lines. i still dont understand what it is for and so i dumped some out so it wont over flow no more but not sure if this is going to fix it for good. i look in the other make forum and it dont look like anyone is ever in there so if any of you have any idea what the hell this thing is and know a way to fix it let me know. what it does is when your pumping gas it causes the gas to spit up back at you just a few sec. after pumping and takes 20 minutes just to pump $10 worth of gas.
