• Replacement of a failed original fuel tank sending unit

Installation Notes

Before installation, inspect and clean the fuel tank as noted in the fitment data. For listed applications, replacing the fuel tank lock ring and seal is required where specified; failure to do so voids warranty on those applications. Verify tank configuration, including 24-gallon capacity, 3-outlet layout, and fuel return or A/C requirements before ordering.

Quality Assurance

Spectra Premium fuel tank sending units are engineered and manufactured with quality control processes intended to meet or exceed the performance of the original equipment they replace. This FG10A is built for consistent operation in the specified GM applications and is backed by the warranty conditions noted in the fitment details.
