Installation Notes

Verify tank configuration before installation, including fuel return, outlet count, and A/C-related application notes. The fuel tank must be inspected and cleaned prior to installation. Replace the fuel tank lock ring and seal; failure to do so voids warranty coverage on listed applications. Confirm fitment against the vehicles year, make, model, and tank setup before service.
