Supposedly from the FSM there is a fuel check valve on our cars between the vapor canister and the fuel tank vapor outlet. I can't find it and the FSM gives no clues as to its' whereabouts. Anyone know where this checkvalve hides? From the FSM it looks like it has like a Molly bolt connector that press fits into a hole to support it, but I've gone over the vapor system from front to back and don't see it.

 

Its should be the white round thing inbetween two vacumm lines under the battery area. I may be wrong though. try that
