ABSTRACT:
A float operated fuel vapor vent valve has body structure with an annular mounting flange formed of material weldable to a fuel tank and the flange is spin welded to the tank. The float has surfaces thereon which slidably engage corresponding surfaces in the float chamber to prevent relative rotation of the float with respect to the valve body during spin welding. An optional pressure relief valve in the vent outlet also has surfaces slidably engaging the vent passage to prevent relative rotation during spin welding.
