Fuel leaking from fuel cap

[mezje]

Under hard cornering with anything above ~1/2 a tank fuel leaks from the tank, enough to see it streak down the 1/4 panel. I was flagged for it at a track day and need to fix it before the next one but it has slipped my mind...

I originally thought it would just be the cap but after some googling it seems it could be something like the vapor pipe being blocked or some sort of pressure issue?

Thoughts? TIA

This is a super old post, I randomly stumbled across it. But i think i've been having the same problem too!! I haven't driven the car in bloody ages so I'm not sure if it still happens. But did you find a fix for this?

Replaced the whole neck and that fixed it. I think they butcher the port at the end to allow for the flap. I found another with a flap but it did fix it.

Ah okay, i'll give that a shot, cheers!
