    What happens when gas tank gets overfilled?

    I'm talking a little over one additional gallon above the automatic cat-out. There is a vapor recovery system and some char-coal canister and whatever else... So what happens when this "stuff" gets flooded? Anyone familiar with this and what happens? (Hint: I know the answer...) I'll have an "attaboy - or -girl for whoever comes up with the right ideas.
    You can't have everything - where would you put it?

    Where the excess goes also depends on your locale's regulations of vapours. In my area it can be a waste of money.

    If you "overfill" the tank while pumping, the excess gas is picked up by the gas pump and goes back into the gas station's tanks.

    If you fill your car absolutely full, flooding the vapor collector in the car, the gas will expand in the tank and give you bad gas mileage. Then your muffler bearings explode.

    So why are you posting this question if you know it already? I don't understand lol.

    False. If the pump could "suck back" excess fuel, that's a tremendous fire hazard. A small fire on the pavement could be drawn back down to the station's main tanks... instantly causing a really bad day for the fire department. There are check valves in the pump to prevent this.

    The gas pump uses an ingeniously simple mechanical vacuum valve to shut off the pump when the gas level reaches near the end of the pump nozzle, but if you force the pump back on again, it absolutely will overflow the car's fill tube and spill over the side of your car. You can thank our good friend Bernoulli for this neat little valve.

    OK yeah, I was referring to the vapor recovery system. But I see the idiocy in my statement. Thanks man lol

    I guess if you have a faulty gasket on the hatch that you open to replace the pump that it could spill in the cabin of the car....but then you have other problems, one being that you have been sucking gas fumes in your ride and not fixing it.

    The gas trickles back into the gas pump handle, where tiny elves live at exactly the halfway point. These elves thrive on incoming gasoline, whilst having no use for outgoing gasoline. Once the incoming gasoline gets to the tiny elves, they mate with the particles, creating Charlie Sheen.

    lol

    Last time, and only time, my tank got overfilled, the station attendant actually did it because the pump was malfunctioning - charging me without pumping any gas...he kept forcing the pump and eventually gas was coming out all over the ground and all over my car. My car didn't drive any differently for many years to come so not sure what happens other than a stinky mess.

    Was this a WRX? I'm asking this for a real reason...
