Abstract
A fuel vapor vent valve is formed of different plastic material than the fuel tank. A U-shaped or cupped attachment member formed of tank material is received over the valve with the upper end slotted to permit the hose fitting to extend outwardly through the slot for hose attachment within the tank. The rim of the attachment member is secured by weldment to the undersurface of the upper tank wall.
