Fuel vapor removal system (Hyundai Elantra J2)

1. If the vaporized fuel vent line is clogged or damaged, vaporized fuel will be released into the atmosphere, thereby increasing the harmful emissions from the vehicle. Disconnect the pipe at both ends and blow it out with compressed air. Remove the filler cap and check that it is properly installed in place.

2. The operation of the transfusion limiter should be checked (two-way valve), installed on the evaporation line between the fuel tank check valve.

When the tank filter becomes clogged, the volume of purified air decreases, so the tank should be replaced.
