Fuel tank pressurised

[Woodgrub]

Hi, I have noticed my GTI has a pressurised fuel tank lately and a very strong smell of fuel. Can anyone tell me how to fix this problem?
Cheers

That’s what it’s meant to do.
Fuel systems are designed to breath in, not out.
It’s a problem if your tank sucks in air when you open the cap. That mean your purge valves and evap systems are not working.
