ABSTRACT:
A fuel filler pipe seal includes upper and lower portions and a sealing lip positioned at the juncture of the upper and lower portions to engage an outer surface of a fuel nozzle and prevent the escape into the atmosphere of fuel fumes during a fueling operation. The lip lies in a plane which intersects a groove formed in an outer surface of the seal to receive a seat formed on a mounting bracket mounted in an upper end of the filler pipe, and the upper portion of the seal has an umbrella valve formed integrally with it which covers a vent opening in the bracket and is preloaded to release at a predetermined pressure. By positioning the sealing lip adjacent the seat-receiving groove a better seal with a fuel nozzle is formed, premature release of the umbrella valve is avoided, and damage to the seal when the nozzle is thrust into the filler pipe is minimized.
