Abstract:

A venting system for a tank in the form of a vapor bypass tube which is interfaced with a melt plug such that the bypass tube provides vapor pressure bypass of the melt plug hole. The vapor bypass tube has a first end mounted to the tank body circumscribably in relation to the melt plug. The vapor bypass tube has a second end, opposite the first end, which is open and located deep inside the tank. A vent aperture is provided in the vapor bypass tube adjacent the first end which provides vapor displacement from within the vapor bypass tube when the tank is being refueled.
