Last week my rear tank filled my front tank. Now I started it up and killed it, almost like I flooded the engine. It was acting like I needed a carburetor adjustment, but its fuel injected! I popped the hood and my girlfriend felt something leaking on her feet from underneath. There is gas flowing out of the charcoal canister. Mainly only from one of the caps, and not from the vabor lines, but when I revoved those they appear to have gas in them also. What do I do to fix this? Is it a fuel relay or a pump issue?
