Installation Notes

Before installation, inspect the fuel tank and clean it thoroughly. The fuel tank lock ring and seal must be replaced; failure to do so voids the warranty. Verify the tank opening and sender mounting area are clean and ready for assembly before installing the FG117A.

Quality Assurance

Spectra Premium fuel tank sending units are engineered and manufactured with quality control processes intended to meet or exceed original equipment performance. Warranty coverage applies only when installation requirements are followed, including replacement of the fuel tank lock ring and seal and proper tank inspection and cleaning.
