Abstract
Methods and systems are provided for a conical guard for an evaporative emissions control (EVAP) system. In one example, the conical guard is arranged at an end of a vent line of the EVAP system, adapted with openings sufficiently small to hinder entry of foreign bodies into the vent line. The conical guard is further configured to trap and expel debris and maintain a desired rate of flow through the EVAP system.
