Installation Notes

Inspect and clean the fuel tank before installation. Replace the fuel tank lock ring and seal during service; failure to do so will void warranty coverage. Verify driver-side mount and two-outlet configuration before installation. The FG05J is also referenced by part numbers SU477 and TNKFG05J for the same application.
