The one part we hope that you buy but never need to use!
JEGS roll over vent valves are designed to prevent fuel from exiting the fuel tank through the vent in the event of a rollover. Available in an internal/bulkhead style which requires a hole to be drilled for installation or an external style which is designed to screw onto an existing male vent fitting. Required by many racing associations. Please consult your rule book or safety committee.
