Detailed Product Description

The Dorman 577-043 fuel tank filler neck is engineered to meet the specifications required for Ford Explorer and Mercury Mountaineer vehicles. Its 37.25-inch length provides an exact fit, ensuring proper alignment and connection to the fuel tank. The steel construction offers resistance to corrosion and wear, which is critical for components exposed to fuel and environmental elements. The 1-inch inside diameter fill pipe supports efficient fuel flow during refueling, reducing the risk of spills or slow fill times. This part does not include a fuel cap, so the existing cap must be reused or replaced separately.

Common Applications and Problem Resolution

• Replacement for damaged or corroded fuel filler necks on Ford Explorer and Mercury Mountaineer
• Fixes fuel leaks caused by cracks or holes in the filler neck
• Resolves issues with improper fuel flow during refueling
• Addresses fitment problems due to worn or bent filler necks
• Prevents fuel vapor leaks that can trigger check engine lights

Installation Notes and Tips

When installing the Dorman 577-043 fuel tank filler neck, ensure the vehicle is parked on a level surface and the fuel system is depressurized. Carefully remove the old filler neck, inspecting surrounding components for damage. Align the new steel filler neck properly to avoid stress on the fuel lines. Since the fuel cap is not included, verify that the existing cap seals correctly to prevent vapor leaks. Tighten all clamps and connections securely to maintain a proper seal.
