Specs At A Glance

Good To Know

Q: How does the rollover valve mechanism work? A: The valve contains a weighted internal ball that blocks the vent orifice when the vehicle tilts past a specific angle or rolls over, stopping fuel leaks.

Q: Can this valve be mounted horizontally? A: No, this safety vent valve must be mounted vertically at the highest point of the fuel tank to function correctly and prevent fuel from blocking the vent.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
