Difficulty: Intermediate · About 55 min · Buick Regal

Replace the fuel filler neck on a Buick Regal by separating its vent and fill hoses, then checking the connections carefully for fuel odor or leaks.

Steps

1. Prepare the vehicle and disconnect the neck

   Work outdoors or in a well-ventilated area away from flames and sparks. Remove the fuel cap and filler bezel fasteners, then loosen the hose clamps and free the vent connection.

2. Remove the old filler neck

   Support the vehicle securely, remove the neck bracket fasteners, and guide the assembly down through the wheel opening. Carefully work the rubber hoses off the old neck.

3. Install the replacement neck

   Position the filler bezel and guide the new neck into place. Fully seat the fill and vent hoses, align the bracket, and tighten each clamp and body fastener.

4. Inspect fuel connections

   Reinstall the inner fender and fuel cap. Check that hoses are not kinked and fittings are secure; inspect for fuel odor or leaks before starting the engine.

Check your vehicle’s repair manual for exact specifications and fit.
