CIS acting up again

[radek at uniserve.com]

Ze case is solved, as would say inspector Clouseau.  Actually, I feel  
a bit like him (a fool).  The car was out of gas.  I knew it was low,  
but remembered distinctly pouring in a couple of small 4-litre jugs a  
couple of months ago.  So I ignored the low fuel warning and the beep.  
  Well, all that gas had leaked out.  After I moved the car, I noticed  
a small dark spot on the ground - there was a slow drip from the main  
hose that comes out of the fuel tank.
Luckily, it's not winter yet, I can open the garage and get that leak fixed.
Thanks for your suggestions Huw.

Radek.
