An EVAP system is the system in the car that retrieves fuel vapors from the gas tank, as well as the rest of the fuel system. The EVAP system will then recycle these vapors so they can be burned in the engine. The EVAP port is a test port where a vacuum can be attached to check for leaks in the EVAP system.
To the fuel tank
The EVAP Service port is on the firewall on the passenger side, right next to the low side service port for the A/C.

Up on top the engine, passenger side assuming the engine is a 4.3 V-6. The year and engine info would help. You can also look for the small green plastic cap within the engine bay. The valve under the cap is a test port for the EVAP system. Follow the line to the engine from the test port. It will lead you to the EVAP purge valve.
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.
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. Ensure all connections are secure to prevent leaks, and then activate the smoke tester to fill the system with smoke. 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.
