Installation Notes and Tips

Confirm the filler neck uses a threaded cam-style cap before ordering. Match the vehicle application carefully, since fitment varies by year, make, and model. For example, this cap is listed for 2007-2011 Toyota Camry, 2006-2008 Lexus RX400h, and 1989-1998 Toyota Corolla applications. Tighten the cap until it seats fully and verify that the sealing surface is clean before installation.
