Fuel Evaporation System: Maintenance

Every 12 months or 15,000 miles, check fuel vapor vent line by blowing through line with compressed air. Also inspect and test valves and clean charcoal canister cover air suction port. Every 5 years or 50,000 miles, replace all vapor lines and charcoal canister(s).
