What It Helps Address

• Fuel vapor leaks that can trigger emission-system concerns
• Improper filler-neck engagement on threaded cam necks
• Cap fitment issues on shallow or deep cam filler necks
• Replacement needs after a missing or cracked fuel tank cap

Installation Notes and Tips

Verify the filler-neck style before installation and confirm the cap threads on smoothly without cross-threading. Tighten until the cap seats properly and follow the vehicle’s normal cap-check procedure. Because fitment varies by model year and configuration, confirm the application against the vehicle listing before ordering. For example, Gates 31832 is listed for many Toyota 4Runner and Tacoma applications, along with select Lexus ES350 and Chevrolet Express models.
