Thanks.
stick your hand round it when you take the cap off and try to feel what way the air rushes.
when my tank breather got blocked on my fiesta si i filled the tank up and when the fuel got low it cut out due to an air lock in the tank lol. when i took the cap off the fuel tank made a funny noise where it was poping back to shape after imploding lol
