System and method for fuel tank tube routing and valve placement to prevent fuel leaks into evaporative emissions system |
摘要 |
Systems and methods for fuel tank tube routing and valve placement to prevent fuel leaks into the evaporative emissions system are disclosed. An embodiment provides a vehicle fuel tank venting system that uses strategically placed valves and a low profile tube routing to prevent the leakage of liquid fuel to an evaporative emission system in the event of a valve failure. In one aspect, a first and second outlet valve may be positioned such that at least one of the valves is above a full fuel level for a desired range of fuel tank tilted positions. Among the desired range, when the first valve is submerged in fuel, at least a portion of the first outlet tube may be above the full fuel level, and when the second valve is submerged, at least a portion of the second outlet tube may be above the full fuel level.
