fuel system pressurising itself

[jackaleks]

is this a normal thing? i replaced the fuel lines on my fd3 yesterday but didn\'t really tighten everything, including the banjo on the secondary fuel rail - not a problem, i thought, no pressure in the fuel system and all these hoses are bone dry. this morning at work i get a call saying that the car\'s dumped a load of fuel on the drive! it\'d been leaking out of that banjo, pooling on top of the housings and then running down, about a litre from the looks of it. i\'m guessing fuel vapour built up pressure in the tank and forced the petrol out? isn\'t there a breather to stop that happening? :confused:
