Meredith Kinee (, New York) - 2003 Hyundai Elantra
A fuel/gas filler question. She fills the tank and it stops every 20 cents. Sometimes it spits it back. It takes a VERY long time to fill. Told it would cost $500 to fix. Guys say the gas vapors can't escape, so tank is telling the pump it's full when it isn't. She needs to have the charcoal canister valve replaced, should cost less than 500.
