  • 13-inch length with a 1.5-inch inside diameter fill pipe

Detailed Product Description

This fuel tank filler neck by Dorman is specifically designed for Dodge Ram 2500 and Ram 3500 models, providing a precise fit and reliable fuel delivery. The steel construction offers strength and resistance to wear, while the 13-inch length and 1.5-inch inside diameter fill pipe accommodate standard fuel flow requirements. The single metal tube vent line helps maintain proper tank pressure and prevents fuel spillage during refueling. Although the fuel cap and mounting hardware are not included, the twist-type cap compatibility ensures ease of use with existing caps.

Common Applications and Problem Resolution

  • Replacement for damaged or corroded fuel filler necks on Dodge Ram 2500 and 3500
  • Solves fuel leakage issues caused by cracked or worn filler necks
  • Restores proper venting to prevent fuel tank pressure buildup
  • Addresses difficulties in refueling due to misaligned or bent filler pipes
  • Ensures compatibility with both gasoline and diesel fuel systems

Installation Notes and Tips

Installation requires removal of the old filler neck and securing the new Dorman 577-346 in place. Since mounting hardware is not included, ensure you have the necessary clamps and fasteners before beginning. Verify the vent line connection is secure to maintain proper tank ventilation. Check for any fuel leaks after installation and before operating the vehicle.
