Abstract
A fuel tank protection valve includes a pendulum type weight that hangs within a bearing socket located below the vent line opening in a fuel tank vapor collection dome. When the vehicle tilts significantly from the horizontal, the weight pivots within the socket, kicking a float ball up to seal the vent line opening. The closing angle of the valve may be easily varied, without changing the shape or size of the bearing socket, by varying the offset from the socket pivot point of the bearing socket of an extension of the weight that actually engages the float ball.
