Dorman 577-947 - Fuel Filler Neck

At last, pump gas with the assurance that you're helping protect the environment while you save money. Designed to prevent fuel leaks during fill ups and to therefore diminish the associated likelihood of air and roadway pollution, it resists moisture build up. Rust, corrosion, and the deterioration they cause are averted. Keep expensive, potentially hazardous gas where it belongs: in your tank.
