A few questions for the experts:
When the ICV resets after an engine shutdown, is it suppose to close 100% to the intake in order to keep vapor from entering the intake until engine start up?
At what point is the pressure regulator venting to the intake? When the engine is running? When the engine is off? Both?
Why does the pressure regulator vent directly beneath the pressure sensor?
The vapor line that runs from the VST to the vapor canister has an inline device in it. Is this a filter or a check valve? Does this ever need to be replaced if it is a filter?
Do vapor canisters ever go bad?
The atmospheric side of the vapor canister: Which way does this flow? From cowling to canister? Or is it from canister to cowling?
