Dorman 577-961 Fuel Tank Filler Neck Direct-Fit Replacement

The Dorman 577-961 Fuel Tank Filler Neck is a direct-fit replacement designed to restore the fuel-filling pathway between the fuel cap and the fuel tank. Over time, the original filler neck can develop rust, corrosion, or cracks — leading to fuel leaks, evaporative emission failures, or a check engine light. This Dorman unit is engineered to match the original equipment specifications for a reliable, long-lasting repair.

Key Features:

• Direct OE Replacement: Precision-engineered to match the original filler neck in fit, form, and function
• Durable Construction: Made from corrosion-resistant materials to withstand fuel exposure and harsh underbody conditions
• Emission Compliant: Built to meet current evaporative emission standards and designed to pass state inspections
• Powder Coated Steel: Provides added resistance to rust and environmental wear for extended service life
• Leak Prevention: Engineered to create a secure seal and prevent fuel leaks during fill-ups
• Backed by Dorman Engineering: Designed and quality-controlled by Dorman's U.S.-based engineering team
