To hook up a smoke tester on an evaporative emission (EVAP) system, connect it to the EVAP service port, which is typically located on the carbon canister or along the EVAP lines.

This will help identify any leaks or faults within the EVAP system by observing where the smoke escapes. Always refer to the vehicle's service manual for specific instructions and locations.

The EVAP service port should generally be closed when not in use to prevent contaminants from entering the system and to maintain the integrity of the evaporative emissions system. It should only be opened when performing diagnostic tests or service procedures. After servicing, it should be securely closed to ensure proper system function and prevent leaks. Always follow manufacturer guidelines for specific procedures related to the EVAP system.
