Hi all 
I have recently acquired an XJ600N, runs fine but has what seems to be a common problem .... oil dripping from the airbox drain pipe. I've read up and thanks to many am clear on what I need to do ..... except for one thing .... 
   When removing the fuel tank, there has been no mention of setting the tap to 'off' ( dont think there is an 'off') or draining the tank before disconnecting the pipe. Maybe im being a bit dense, but what stops the fuel running out all over the place?? 
 
Many thanks, in advance.
