Dorman 577-089 OE Solutions Fuel Tank Filler Neck Replacement

The Dorman 577-089 Fuel Tank Filler Neck is a precision-engineered OE Solutions replacement designed to restore proper fuel system function. Fuel filler necks are constantly exposed to road debris, moisture, and corrosive elements, making them prone to rust, cracks, and leaks over time — symptoms that often trigger a check engine light or result in visible fuel seepage at the fill point. This direct-fit replacement eliminates those issues with a durable, vehicle-specific design.

Key Features:

• Direct OE Replacement: Engineered to match the original filler neck geometry, mounting points, and connection interfaces for a straightforward, no-modification installation
• Corrosion-Resistant Construction: Built from durable materials designed to resist rust and deterioration for long-lasting reliability
• Emission Compliant: Designed to meet current evaporative emission standards and pass state inspection requirements
• OE-Style Cap Interface: Accepts the factory gas cap and installs in the stock location without modification
• Quality Tested: Thoroughly tested to ensure fit, form, and function match original equipment specifications

Backed by Dorman's engineering and quality control teams, this filler neck delivers a dependable repair that restores fuel system integrity.
