Is a leak from the top of a gas tank dangerous? ?

It only leaks when the tank is full and the car is at a tilt. Is this unsafe to drive?


It's a 2005 honda CRV. 

Very slow drip.

    Leaking gasoline can never be a SAFE condition. 

    If this happens regularly, maybe the gas cap seal is injured.  Check and replace if needed. 

    Or you have a tank under the middle of your car that has a fill hose from the top of the tank leading up to a fill cap on the side of your car.  Maybe the hose clamp is loose or broken or the hose is damaged.  In some vehicles, you can access the top of the tank from under the car, but most cars you'd need to disconnect the gas tank straps and lower the tank a few inches to see or access the hose/tank connection. 

    You could/should stop filling your tank so full.  Also, are you squeezing in as much fuel as is possible on a fill-up???  That could be making a bad situation worse. 

    Ask at a dealership.  Maybe it's a common problem for your car model.  Maybe they have a "fix"? 

    Why don't you identify your car for us?

    I have seen this with some older cars, but most newer ones are plastic tanks now.  We used to just make sure to not have any more than 3/4 of a tank, never filling it up.  Modern cars will throw a code or say to check gas cap because the tank fumes are not being collected.

    Any gasoline leak is dangerous. Only fill the gas tank half way until you get it fixed.

    Any time a car is leaking gasoline it is dangerous regardless of where it is leaking from.
