    I'm having problems to fill up the fuel tank of my Hyundai Sonata 2000. When I try to put fuel on it, it starts to overflowing the fuel, no matter the car is almost empty.
    Can anybody help on this?

    When fuel goes in, air must come out.
    The Evap system has a vent valve after the charcoal canister.
    The vent valve or charcoal canister may be blocked
    Also don't forget about the purge valve.
    Check the parts to see if they are blocked or not functioning properly

    My friend just replace his canister ... sale price of $197 dollars
    Have read other forums and plenty of people mention the purge valve
    Not sure how that would affect it??

    What people are telling me is that the purge valve would cause hard starting if not working proper
    The valve near the canister is the vent valve
    It is normally open to allow for air to flow out of the canister which comes from the tank
    Purge valve is usually in the engine bay near the in take plenum/throttle body
    And it is normally closed
