Difficulty: Intermediate · About 45 min · Honda Civic

Replace the fuel filler neck on a Honda Civic by releasing its hose clamps and wheel-well liner, then inspecting each connection for fuel leaks.

Steps

1. Raise the vehicle and remove the wheel

   Loosen the lug nuts while the tire is on the ground, raise and support the vehicle securely, then remove the wheel and wheel-well clips.

2. Disconnect and remove the filler neck

   Pull the inner fender liner aside. Loosen the large fill-hose clamp and smaller vent clamps, remove the neck bracket bolts, then guide the old neck out.

3. Install the new filler neck

   Guide the replacement into position and secure its body brackets. Seat the fill and vent hoses fully, position the clamps behind their hose beads, and tighten them.

4. Reinstall trim and inspect

   Restore the wheel-well liner and clips, refit the wheel, and tighten its fasteners to specification. Check the cap seal and hose joints for fuel odor or leaks before starting.

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