Vapor system basics
The evaporative emissions system collects fuel vapor from the tank and stores it in a charcoal canister until the engine can burn it. Seals and hoses at the canister and tank connections keep that vapor from escaping. When a seal hardens or cracks, fuel odor, leaks and emissions-related warning lights can follow, so it is worth checking the connection area during any service.
Because the same system uses hoses, clamps and valves, a seal replaced alone can leave an older leak elsewhere. Inspect the surrounding parts before reassembly, and check the connection for debris that could prevent a tight seal. Work near the fuel system should be done away from open flames, with the tank drained as far as practical.
- Check the canister and hoses for cracks
- Clean both sealing surfaces before fitting
- Watch for fuel odor after the job
