Product Details

The Dorman 577-948 is a direct-fit replacement fuel tank filler neck constructed from steel with a black finish. Fuel filler necks are exposed to harsh under-vehicle elements over time, leading to corrosion, rust, and eventual failure — symptoms often include leaking fuel or an illuminated check engine light. This Dorman unit restores proper sealing and fuel delivery function with an OE-matched design.

Key Features:

  • Direct OE Replacement: Precision-engineered and thoroughly tested to match the original filler neck geometry and fitment
  • Durable Steel Construction: Built from corrosion-resistant materials to reduce the likelihood of future failure
  • Emissions Compliant: Meets current emission and inspection standards
  • Approximately 18.3 inches in length — sized to match original equipment specifications
  • Sold individually — fuel filler cap not included
  • UPC: 019495272328

Backed by Dorman's U.S.-based team of engineers and quality control experts, the 577-948 filler neck delivers reliable, long-lasting performance as part of Dorman's OE Solutions product line.
