V6 Petrol, Quick question about fuel tank.

Hi,
Can someone out there in Bongo land please answer this question for me. Should the fuel tank on a petrol fuel injected vehicle be pressureised? When I remove the filler cap it always releases pressure. Is this something that is required in this type of fuel system. I'm just a little concerned as if the tank isn't supposed to be under pressure I don't want the prospect of the tank & pipe work potentially developing a leak because if it.

Cheers

Yes mine does the same! I assume its the returned unused fuel from the injectors which are of course under pressure.
