Abstract
Provided is a fuel cutoff valve that reduces the emission of fuel vapors from within fuel tanks. The fuel cutoff valve is mounted by partial insertion into a fixation hole provided in an upper tank wall of a fuel tank. The fuel cutoff valve comprises a cover, a casing, a float, and a spring. In the cover, a matrix of polyacetal having excellent resistance to fuel permeation reduces emission of fuel vapors into the atmosphere, while a dispersed phase of polyethylene in the matrix allows welding to fuel tank.
