Dorman 577-248 OE Solutions Fuel Tank Filler Neck Steel - Black

The Dorman 577-248 is a direct-fit replacement fuel tank filler neck engineered to restore proper fueling function on compatible vehicles. Constructed from corrosion-resistant steel with a black finish, this filler neck is precision-manufactured to match the original equipment dimensions and routing for a hassle-free installation.

Fuel filler necks are exposed to moisture, road salt, and harsh underbody conditions that cause rust and deterioration over time. Common symptoms of a failing filler neck include fuel odor, visible leaks around the fill point, difficulty seating the gas cap, or an illuminated check engine light triggered by evaporative emission faults. This Dorman replacement resolves those issues with a durable, OE-matched component.

Key Features:

• Direct replacement — matches original equipment specifications for a bolt-in fit at the factory mounting location
• Steel construction — corrosion-resistant material with black finish to reduce future failure potential
• Emission compliant — built to meet current evaporative emission and state inspection standards
• Accepts OE gas cap — designed to work with the factory fuel cap
• Sold individually — fuel cap not included
• OEM cross-reference: Nissan/Datsun 172218B400; Spectra Premium FN912

This filler neck is part of Dorman's OE Solutions line, backed by a team of U.S.-based engineers and quality control specialists. It provides a reliable, cost-effective alternative to sourcing a discontinued or expensive OEM part.
