Fuel tank vacuum F4i

Fuel tank vacuum F4i
Hi all,
I seem to be getting a rather strong vacuum in the tank after a long run, making the fuel cap hard to open and a large amount of air floods in when it finally does open.
Assuming that the F4i (F1 in the UK) has a tank breather, is the tank breather in the fuel cap or elsewhere on the tank? Figure I should check it for blockages.
Thanks in advance.
