Fuel Injected Engine: Turbo

Fuel travels from fuel tank to canister in the same manner as fuel injected models without turbo with 2 differences. When turbo is in effect, purge control valve is closed by a return spring. Also, an additional purge line purges vapor into the air intake boots when the engine is running.
