Capless refueling system

摘要

A capless refueling system is provided which utilizes snap-in attachment of a multi-stage valve assembly within a fuel pipe. The valve assembly includes a lower body portion and a cover independent from the lower body portion. The lower body portion and the cover are configured to be lockingly adjoined to one another. The cover is adapted to be adjoined to the fuel pipe. The system is sealed at a position above the primary shutoff valve thereby eliminating the need for a spring pin support bracket.
