Product Details

The Dorman 577-379 Fuel Filler Neck with Tube is a direct-fit replacement designed to restore your vehicle's fuel delivery system. Fuel filler necks are constantly exposed to road salt, moisture, and temperature extremes, making them prone to corrosion and eventual failure. Common symptoms of a failing filler neck include fuel odors, visible leaking around the fuel door area, and illuminated check engine lights caused by evaporative emission system faults.

Key Features:

  • Direct replacement for worn or corroded original equipment
  • Engineered to meet or exceed OEM specifications for proper fit and function
  • Complies with current evaporative emission standards (EVAP)
  • Constructed from corrosion-resistant materials for extended service life
  • Includes integrated tube assembly for complete repair solution
  • Designed for straightforward installation using basic hand tools

This replacement filler neck eliminates fuel leaks and restores proper fuel system integrity, ensuring your vehicle passes emission inspections while preventing fuel vapors from escaping into the atmosphere. Dorman's engineering focuses on improving upon original designs to provide a durable, long-lasting repair that addresses common failure points.

AMAZING SERVICE! I received the parts the next day! Love it, good products, great quality, amazing price. Customer service responded within minutes of me sending an email with questions.<br><br>GOOD JOB GUYS!

Cool

This was my first order with Autoplicity and I am very happy. They had the lowest price on-line that I found. Communication was great and shipping was very fast. I ordered late on Thursday and it was at my house the following Tuesday, and I didn't pay for rush shipping. I got exactly what I expected. Will do business with these guys again.
