Who is correct regarding the fuel cap functional test?

Explanation:
The fuel cap functional test is about making sure the EVAP system seals properly and can hold pressure. When a cap adapter is available, the test should be performed on every vehicle to verify that the cap seals correctly and doesn’t allow evaporative leaks. This isn’t optional or limited to certain types of vehicles; the adapter enables a controlled pressure check, and a failing cap or seal can cause EVAP leaks that affect emissions readings. So, with the adapter on hand, the correct procedure is to test all vehicles to confirm proper fuel cap function.
