A direct-fit replacement gas flap for 1970-1973 Nissan 240Z, designed to restore the factory appearance and protect the fuel filler opening.

Built for durability and ease of installation, it’s ideal for restoration projects, routine maintenance, or anyone replacing a worn or damaged filler flap on a classic 240Z.
Features:

  • High-grade stamped steel construction with a corrosion-resistant finish for long life
  • Protects the fuel filler opening from water, dirt, and road debris
  • Restores factory appearance and function for restoration or maintenance projects
  • Simple bolt-on installation with common hand tools
Installation / Application:
  • Difficulty: 2/5
  • Estimated time: 15-30 minutes
Suggested Tools:
  • Phillips screwdriver or flathead (depending on fasteners)
  • 8mm/10mm socket and ratchet
  • Penetrating oil (if fasteners are corroded)
  • Clean rag
  • Small trim pry tool (optional)
  • Anti-seize or thread locker (optional)
Instructions:
  1. Park on a level surface, shut off the engine, and open the existing gas flap.
  2. Inspect the existing fasteners and surrounding area. Apply penetrating oil if bolts appear corroded; allow to soak.
  3. Remove the fasteners securing the old gas flap using the appropriate screwdriver or socket. Keep any reusable hardware.
  4. Carefully lift off the old flap and hinge assembly. Use a trim pry tool if needed to break any paint adhesion.
  5. Clean the mounting surface of dirt, rust, and old sealant with a rag and light rust remover if required.
  6. Position the replacement gas flap over the mounting holes and align it with the filler opening and body contours.
  7. Install the fasteners by hand to ensure proper thread engagement; then tighten snugly with the screwdriver or socket. Apply anti-seize or thread locker if desired.
  8. Cycle the flap open and closed several times to confirm smooth operation and proper alignment. Make small fastener adjustments if needed.
  9. Check the fuel cap seal and filler access to ensure the flap does not interfere with the cap or fuel nozzle.
  10. Wipe down the area and touch up paint around fastener heads if necessary to prevent corrosion.
