The invention relates to a vapor seal member adapted to be received within the filler neck of a fuel tank. Normally, such filler necks are cylindrical in shape and sufficiently long to receive a corresponding discharge tube section of a fuel dispensing nozzle. The filler tube further includes a terminal rim at the outer edge to removably receive a closure cap. The vapor seal member includes a peripheral lip which firmly engages said terminal rim of said filler tube. A central resilient segment of the seal member defines an access opening adapted to slidably receive the discharge tube of the nozzle whereby to form an annular vapor tight seal with the latter and thus avoid passage of fuel vapors from the tank.
