Installation Notes and Tips
Verify the vehicle uses a return-type gas fuel system before installation. Confirm the Tacoma model year and build date match the listed fitment, especially for 2012 Tacoma from 11/11. Use the reference port to check fuel pressure after installation and confirm the regulator is mounted securely with the bolt-mount design.
