Hi,
I somehow managed to overfill my 0,9 Cinq. Second fill up with a brand new fuel tank. Came home, parked it and the fuel was literally spraying from the bottom. Removed the diamond shape cover and found that a pipe at the front of the tank was leaking. I was told that iťs an overfill pipe and that when the fuel level will drop It will stop. There´s third less fuel in the tank and it´s still leaking. Mostly when I´m going up a hill or through a tight bend, but also when I stop the car after a longer drive. What do I have to do to stop it?

That pipe should run to the top of the filler neck.
It shouldn't just be an open pipe....!!!
Just for my clarification, the circled tube is not an overfill pipe? I was writing about this one

Yes, that pipe should have a hose connected to it which connects to the top of the filler neck.
It is a sealed system You would NEVER have a open pipe on a fuel tank.

I did, but there is a rubber hose connected to it, its just leaking
ok
Fuel will get through any tiny leak as it is so thin.
If the hose isn't split it may just need sealing better.
I had similar when I changed my main filler pipe.
I used Hylomar Red on the connection before pushing the pipe on and clamping it.

Thank you for your help! And what is the purpose of the rubber hose?
