Disconnect the fuel vapor tube-to-EVAP canister purge valve quick release coupling.
Refer to: Quick Release Coupling (310-00A Fuel System - General Information - 1.5L EcoBoost (118kW/160PS) – I4, General Procedures).

NOTE:
If smoke does not exit the fuel tank filler pipe
neck area after the system is pressurized, open the canister vent
solenoid with the scan tool to allow the air to purge. Once smoke is
seen at the canister vent solenoid, close the canister vent solenoid
with the scan tool.
Introduce smoke from the VACUTEC Smoke Machine Fuel EVAP Emissions System Tester into the EVAP
system and verify that smoke is exiting the fuel tank filler pipe neck
area. For additional information, refer to the manufacturer's
instructions.
-
Remove the supplemental refueling adapter once smoke
is observed exiting the fuel tank filler pipe neck area.
-
Continue to enter smoke into the system for 60 seconds to obtain pressure.
-
Press and release the remote start button in
intervals of 15 seconds ON and 15 seconds OFF while checking for exiting
smoke.
-
Use the halogen light provided with the VACUTEC Smoke Machine Fuel EVAP Emissions System Tester to follow the EVAP system path and look for smoke exiting at the source of the leak(s).
-
Repair any leaks as necessary.
-
Repeat the leak test until the system passes.
