I had a petrol leak recently on my 8V digi. It turned out to be the rubber hose that feeds to the injector rail. Replaced it with one from Halfords (7.6mm), was under a tenner and included new hose clips too.
Take off that big rubber boot that runs from the airbox and you'll be able to see clearly. Mine was a Digi though. I think K-jet is different.
Also, mine was only a tiny leak but I could still smell it. If yours is dripping then surely it would absolutely stink and allow you to determine if it is petrol or power steering? Having said that, my PAS leaks too but it doesn't smell!
