Ok, I believe I may be an idiot. I own a 1999 MkI Skoda Octavia with a 1.8 20v Engine. And I thought, abit of preventative maintainance would be appropiate. Changing the oil and such. That bit is the easy one. I wanted to cleean the fuel line...but, I have no idea which connection it is..WIthout spending 18 quid on a haynes manual I have no idea which hose the fuel supply line is? Any ideas?

Why do you want to clean the fuel line? The filter should keep the fuel supply clean. The filter should be changed at one of the service intervals.

Indeed mate. Change the fuel filter sure, but the lines aren't normal maintenance items.
