#1 - Fuel Evaporative Emissions Control System - F.I. models
1. Throttle Body | 4. Vapor/Liquid Separator |
2. Charcoal Canister | 5. Fuel Tank |
3. Two-Way Check Valve | 6. Fresh Air |
Do you smell gas under the hood, but there are no gas leaks (verified). Then usually the Charcoal canister has outlived its usefullness, so replace it.
The canister is connected to a solenoid that (which is normally closed).
When the engine is started, it is opened to intake the the vapors that
are stored in the canister, through a special port on the carb. TBI, or
MPFI unit. On F.I. models, this system is in operation continually
while the engine is running, and there is no solenoid valve.
