hi,when i take the petrol cap of my sei sport i get no siss noise,(like its not pressureised) then when i try to put the cap back on it won;t lock back into position until after a minute or so.any suggestions cheers:)
 
My previous car was an Uno and it let pressure out every time I opened the petrol cap , mostly in the summer when the weather was hot , since I've had my scie (2 years) I have yet to hear this so I don't think there is a problem. If it ai'nt broke don't fix it ..
 
yes the wd40 usually does the trick, as for the hiss a fuel tank has a breather to it and i dont think there is any form of one way valve so in theory there should never be a hiss anyway. :)
 
hmm good point ...

But in the haynes manual, when u change your fuel filter, it tells u to depressuise the fuel system first.

So are there no pressure at all then ??

Thanks

the pressure they take about in the manual is from the fuel pump onwards mate ;)
after the engine is turned off the pressure can still be held in the lines going from the pump to the TB
 
haahhahha not good idea, if your brother smoke :p

no but there will be fumes in the air anyway if your changing the filter,pressure in the line or no pressure! the filter will be full of fuel which will end up on the floor.
ive made a few run way attempts from people changing a filter at work while someone else is welding!! :eek:
scary stuff haha.
 
hahahahahahahhahaahhahaha i can imagine u running away from a line of fire, shouting " **** **** **** **** "

Hhahahahha
Thanks¬!!!!! That cheer me up
