Fuel bowl is now externally vented. This goes to a special 5-hose Charcoal Canister. The canister has a Vent Switching Valve which is open when the engine is not running, so that vapors from the fuel bowl can go directly to the charcoall filter. When the engine starts, vacuum from the intake manifold closes the VSV.
