Fuel pressure

[bro973x]

My car has always had pressure in the tank but after yesterday when the cap nearly flew off at the station, I am wondering if this is supposed to be like this?? Someone suggested to me that there must be a vent blocked in there and if so, Where is it? As always ,I will be very grateful for any advice, thanks...

There is a vent hose from the top of the tank sender unit rising to just below the filler neck and also an evaporative hose from the tank itself leading to a check valve. Normally none of this would cause problems.

Is the fuel return line complete and unkinked?

I have the same issue, but it does not seem to affect the car.
