Hi,

I know this sounds stupid. But this is what happened.
I was trying to pour a bottle of fuel injection cleaner into my 98 A4 quattro 2.8L into the fuel tank after an oil change.
But I found that the fuel tank has some kinda seal...which blocks the fuel injection cleaner from going in.
Do I need some kind of special tool to do this? I simply cannot make the fuel goes in. If you have any advice please let me know

thanks
