    Vacuum in Fuel tank

    No, I haven't got a Hoover stashed in the tank, but when I try to open the tank to fill up, there is quite a strong vacuum effect making it difficult to open the cap.

    Is this normal or have I got a trapped/blocked breather?

    Any advice appreciated.

    Thanks gents - I don't fancy a sucked-in tank!   :005:

    I lifted the tank this evening and made sure that the breather hoses aren't blocked, (they're not), so made sure that they are not getting pinched when I put the tank back down. 

    I'll find out if its sorted when I go to work tomorrow.  If not, the tank will have to come off for some more in depth faffing-about!

    Just a quick update - no more vacuum problems since I lifted the tank and checked the breather hose routing.  I can only assume that the breather hose was crushed/bent for some reason, but no idea why it happened, because I've not had the tank off for months.
