Just started the engine for the first time this year and noticed a steady stream of fuel coming out of the lower cowling. Removed the engine covers below the engine head and there is a vent line coming from the top of the engine that begins a stream of fuel as soon as the engine starts. Looking at the diagram, it appears to be coming from the Vapor Separator Tank. Any suggestions? Thank you.

Clean the VST and check the hoses are not clogged.
